Express.js cookie setter's Domain attribute: how to share cookie with *multiple* domains?

Let's say you have the following cookie setter:

res.cookie('name', 'tobi', {
    secure: true, 
    httpOnly: false, 
    sameSite: 'None',
    domain: '.example1.com'
});

How would you need to change the domain attribute to share the cookie with multiple domains, and not only with example1.com?

I've tried several options for the domain attribute, but none worked:

domain: "'.example1.com','example2.com'"
domain: ['.example1.com','example2.com']
domain: "['.example1.com','example2.com']"
domain: ".example1.com", domain: "example2.com"

None worked because it's simply not allowed:

Multiple host/domain values are not allowed

Also, if your website is hosted on www.example1.com, your server is only allowed to set cookies for either www.example1.com or example1.com (the latter meaning "example1.com and all subdomains").
