Hi, I am setting up a backend which will have 4 frontends (website), each with their own login and sessions, I am only implementing the session management part of supertokens. This page states that websiteDomain is a compulsory field, and that too for email and password link generation. I am not sure whether these are necessary in my case since I will be handling these email and password reset logic myself, but if they are, which frontend website domain am I supposed to use? Btw my 4 frontends will all be under the same domain, as subdomains, but still each will have their own login and sessions, can I just set my main domain name under that?
