Delegate admin rights?

[HakanLjungqvist]

I am the secretary of a non-profit association and our chairman has a Zoom One Pro license to hold meetings.
He schedules the meeting, starts the meeting at the right time and enables participants to share their screens. After the meeting, he closes the meeting.

Our chairman will now be away for a while and during that time we need to hold a meeting. During this time, he cannot administer the meeting because he does not have access to the Internet.

I have a Zoom Basic account. Can our chairman give me administrative rights to hold the meeting?

He tried to delegate admin rights to me, but it didn't work.
