I think you might be misinterpreting the instructions. I don't think that their expectation is for the linked page to be used to request account deletion, but that it prominently feature the steps required to request account deletion.
For example, let's say you place a "delete my account" option in a menu within your game. My read is that you are required to have an 'explainer' web page that a user could follow to find and use that feature.
