remove unnecessary maybe type union

intended flow: use id fetch function to get role for current guild, use role id to fetch role from discord role cache,
use role in intended use case
currently the role id is hardcoded, needs to be read from some sort of cache which persists the ids in config file
needs to be differentiated by guild id and role type
could be the target of a user configurable frontend in the future
