I didn't added flex-shrink as it was making things overflow

Tested ✅ all good regarding password policy.

Follow-up: remove the action to submit empty password as it's only possible now if you just enable the password radio button (it won't make sense to show "Conversation password has been removed" while you haven't set one yet). I will add this in further refactoring.

Thank you for you contribution 🥳 Looking forward to your next PR.
