BBB: Access code for external users

If the BBB room template supports "Links for external users", an access code for external users can also be generated when creating a BBB meeting.

Implementation:

• Checkbox "Access code" at meeting creation (only when external link is available)
• Default value: Checkbox not activated
• Checkbox activated:
  • Code is automatically generated and displayed (six digits)
  • Code can be overwritten manually (max. 65 digits)

For distribution, the access code is displayed for coaches, course managers, administrators (analogous to the link for externals). Participants do not see the code.

Clicking the external link: add mandatory input field to enter the code. Display message if code is wrong or field empty.
