Yeah Discord is a pain to manage in corporate settings. No SSO, needing to play footsie with Alice creating an invite link so that Bob can join, and only then Alice can attach the correct roles. If people don't use usernames that correspond to their real-life names, then auditing access to ensure users and roles are cleaned up after real-life changes is a huge pain.
Discord is great for small start-ups to help create a virtual office space for remote work, but it really doesn't scale well.
With the evil spawn of spaghetti code that Teams is and its cancerous spread through office offerings I'd take Slack or Discord any day.
