LGTM 👍 just some non-blocking comments for discussion

For the markdown table in the channel-settings list response, we should probably have it say:

Default: Allow meetings in public channels, private channels, and DMs/GMs

or

Default: Allow meetings only in private channels and DMs/GMs

then simply omit any rows from the table that have the "default" value. We could probably just remove that channel from the saved settings map if the user chooses "default". 0/5 on this though

@mickmister the default setting has a dynamic value (i.e. it can be updated in plugin configuration) Didn't get you on this, please explain.

@Kshitij-Katiyar Yes I was suggesting we display this value in the response in the wording I posted above. Just so when someone wants to inspect the settings on a channel, they can know what the default value is. Then we can omit any channels that are either unassigned or using the default value

[Kshitij-Katiyar]

Default: Allow meetings only in private channels and DMs/GMs

this was the existing channel setting list

And this is the updated channel setting list

@mickmister I hope this aligns with your suggestions. Please let us know if anything else is required.
