I have a question about Google Play’s app account deletion requirements

I found this on Google support:

The User Data policy's Account Deletion Requirement means that: All developers must complete new Data deletion questions in the Data safety form on the App content page (Policy > App content) in Play Console. If your app enables account creation, you must: provide users with an in-app path to delete their app accounts and associated data; and provide a web link resource where users can request app account deletion and associated data deletion. You have the opportunity to show users if you delete other data too.

Is it necessary that a player can request the deletion of his account on my website?

If yes, how can I find out if this person is the owner of the account?

I use Azure PlayFab in my game and the player needs to create an account and he can login with his email address and password in my game. But the player cannot login on my website with his PlayFab account credentials, therefore I don't know how to make the player's account deletion from my website. My website is still under construction and not online.
