react-to-role resolution

[sinus-x]

When you have access to the channel and use the # sign, it is saved as channel reference <#123> instead of just plain readable string #foo. As a result, the bot does not find the channel, because it's looking for <123> and not foo.

Solution is not using hash signed names (channels take precedence over roles). To distinguish roles and channels, we can make a mapping (json dict or database), that would map a channel to either roles or channels and wouldn't look for anything else. We could also add an ACL check, so only users with given ACL group would be allowed to get their requested access.
