Hi everyone. Thanks for sharing this gist. Is there any way to open calendar event creation but with a shared calendar selected by default? I've tried with calendarId, folderid, but nothing works.

Thanks

I just realized that you have to URL encode the folder id.

@codingwaysarg Did it work to select a shared calendar with folderId? Which ID do i need to take and URL encode?. Help would be MUCH appreciated.

Is it possible to use compose for recurring meetings? I can't seem to find any official documentation for this yet
