How to add user consent using UserMessagingPlatform

I have a few questions about Google's UserMessagingPlatform.

.

func requestConsentInfoUpdate(in vc: UIViewController, completion: (() -> Void)?) {
    let parameters = UMPRequestParameters()
    parameters.tagForUnderAgeOfConsent = false
    
    UMPConsentInformation.sharedInstance.requestConsentInfoUpdate(
        with: parameters,
        completionHandler: { [weak self] error in
            if error != nil {
                // handle error
            } else {
                if UMPConsentInformation.sharedInstance.formStatus == UMPFormStatus.available {
                    // if it is avaiable (and required) i load the form
                    self?.loadForm(in: vc, completion: completion)
                } else if UMPConsentInformation.sharedInstance.formStatus == UMPFormStatus.unknown {
                    // docs suggest to request another update
                    self?.requestConsentInfoUpdate(in: vc, completion: completion)
                } else {
                    completion?()
                }
            }
        })
}

This function gets called when the first ViewController is presented, takes as parameters the vc itself, which will present the form, and a completion, since I wanna wait for all the privacy stuff before calling GADMobileAds.sharedInstance().start() and requesting ads.

1. How do I handle the under age flag?

Should I ask the user his age before presenting the form? Or should I just assume that the user is not a minor, like most apps do, and keep tagForUnderAgeOfConsent = false ?

2. Infinite recursion?

By docs, from here:

UMPFormStatusUnknown: Whether a consent form is available is unknown. An update should be requested using requestConsentInfoUpdateWithParameters:completionHandler.

Maybe it's a stupid question, since if the docs advice for it then it should be safe, but could this implementation potentially cause infinite recursion?

private func loadForm(in vc: UIViewController, completion: (() -> Void)?) {
    UMPConsentForm.load(completionHandler: { [weak self] form, loadError in
        if loadError != nil {
            // handle error
        } else {
            if UMPConsentInformation.sharedInstance.consentStatus == UMPConsentStatus.required {
                self?.present(form: form, in: vc, completion: completion)
            } else {
                completion?()
            }
        }
    })
}

private func present(form: UMPConsentForm?, in vc: UIViewController, completion: (() -> Void)?) {
    form?.present(
        from: vc,
        completionHandler: { [weak self] _ in
            if UMPConsentInformation.sharedInstance.consentStatus == UMPConsentStatus.obtained {      
                GADMobileAds.sharedInstance().start(completionHandler: nil)
                completion?()
            }
        })
}

Here the form is loaded and presented.

3. Where to pass consensus for mediation partners?

If I understood correctly, UMP pass to its network all the privacy settings under the hood for me once the consensus is obtained. This is just for Google ads, what if I want to use mediation and present also Unity ads, for example? Unity docs explain how, for GDPR consent for example:

let gdprMetaData = UADSMetaData()
gdprMetaData.set("gdpr.consent", value: true)
gdprMetaData.commit()

My question is where should I call this though. From my understanding, UMPConsentStatus.obtained means just that the the user set his preferences, not necessarily that he agreed to targeted advertising.
