Microsoft Calendar - append people

Hello!

Google calendar when Im updating an event got checkbox “append”, that makes my list updated with the person Im adding.
Microsoft calendar doesnt have that, so adding one person replaces existing list of attendees entirely with my new one. Is there a trick for that?

(Im aware I could get an array of attendees first, then add new and push whole array, but Im actually using no-code integration tool to NOT have to do that).

Any help appreciated!
