What type of Authentication we should use inside our DocuSign API integration

Question

I have created a developer account to test our integration with DocuSign API, but i am not sure which authentication option i need to use inside the below screen:-

now in our case we are building a registration system, with the following main requirments:-

• We will upload a contract inside DocuSign and specify that users need to sign the contract.
• inside our application, if the user complete the registration >> to inform docuSign to send the user an email to Sign the contract
• We want the same contract inside DocuSign to be sent to multiple users, and each user will Sign his own contract.

This guide would help you learn all about authentication and which of the various options you should choose and how to set it up in DocuSign Admin.

the simple summary is this:

• If each user of your integration will use a single system account to log in, you should use JWT Grant. Note that, when using JWT Grant to obtain an access token, you can still use elements of the other grants to obtain consent.
• If your integration uses a browser or client to make requests to a web server, it can use Authorization Code Grant.
• If your integration will not use a single system account to log in and does not use a browser or client to make requests to a web server, it must use Implicit Grant.
