Discord Reaction Roles Bot, Self-Assignable Roles
Let members pick their own roles with a click or a reaction, four modes: normal, toggle, unique and verify.

Manually assigning pronoun, game or notification roles doesn't scale past a small server. Wody's reaction roles module lets members grant themselves roles directly from a message, with staff choosing exactly how permissive that should be.
Four modes cover most use cases: normal lets members pick any number of roles, toggle removes a role on a second click, unique limits members to one role from the set, and verify requires a role members already have before they can claim another.
What's included
Normal mode, members can hold any combination of roles from the menu
Toggle mode, clicking again removes the role
Unique mode, only one role from the menu at a time
Verify mode, requires an existing role before claiming a new one
Works with both reactions and buttons
