Why?

sometimes it is inconvenient to grant rights to players in the server console, and it would be easier to just add a role to discord and this group would be granted to the player in minecraft.

What and How?

after the role is issued in the discord, the bot monitors the role issue and synchronizes with the server in minecraft and issues a group in minecraft that corresponds to the issued role in the discord.

Are there alternatives?

currently I don't use any other methods.

Checks

• I have used the search at least once to check if my idea has already been suggested and perhaps already implemented.

Anything else

I hope you will appreciate my idea for your project, because I think it is a useful feature that will be used by other server users.

This is already possible (see https://docs.discordsrv.com/synchronization/ for more details). You can make the Discord roles take priority by setting GroupRoleSynchronizationMinecraftIsAuthoritative to false.
