Explain your idea

In addition to the account linking system, would it be possible to require players to link their accounts before they can actually start playing?
When enabled, players who have not yet linked their Minecraft and Discord accounts should be prompted to do so, being provided an automatically generated link code by the disconnect message.
The specific platform I am utilizing is Fabric (on Minecraft version 1.21), but would be useful for any platform I'm sure.

If this is platform-dependant, which platform is this about?
