Alternate Meeting Hosts

I lead bi-weekly writers workshops. I do not make money from this. Occasionally, I ask someone else to lead the workshop because I'm away or have another commitment. In the past, I was able to give my logon into to that person to start the meeting. Based on recent experience, it seems Zoom has tightened up this path and I won't be able to ask someone else to lead the meeting unless I open it. Is this true? I have already added another licensed use for someone who is leading another regular workshop. To add a third is out of my price range and seems absurd since I only need a substitute facilitator maybe four times a year. Can anybody clarify or confirm this situation for me?
