DISCORD ROLES how to create, edit or delete?

okay so here's discord app so um yeah if you go to server settings here there is a new feature which is called trolls so organize your members use rows to organize your server members and customize their permissions you can have default permissions and then you can create raw so role name you can create like this you can create a raw color you can change image um display roll number separately um allow everyone to mention this role view server as role and then you can set up permissions view channels manage channels manage your roles you audit log manage members and then you can just save changes so then you can just see this role here and then you can just delete also this role from here so that's the idea
