Why?

It's better to send invites, adds a calendar entry + we won't need to allow them to enter everytime.

What to do?

• Add a feature which sends a calendar invite for the template which requires a google meet link. The mail body will become description this time.
  • Take care of the settings, they shouldn't see all the invited members, neither should be able to invite others. Also, other settings must be checked carefully
• If it doesn't have meeting link, then send normal mail (this code part already exist, just need to tweak when to execute).
