You can auto-assign discord roles based on 101 badge ownership. This allows you to restrict certain channels based on who knows what. Here's how you can do that:
With Guild
Create your Guild, link your discord
Select 'Create Guild'.
Next to Discord, hit 'Select server'.
Find your server, hit 'Add bot'.
Authenticate with Discord.
Hit 'Create Guild'.
Walk through the intro Wizard
Hit 'Send Discord Join Button'
Confirm details, hit 'Send'
Create a new role with the 101 integration
Select 'Add role'
Populate the role title and specify which Discord role you'd like to assign (or create a new one)
Under 'Requirements' select the 'Integrations' tab
Select '101' then type in the name of the course
Hit 'Save'
You're done!
If you've done everything properly, you should see the join button like this:
