One particpant unable to be seen in a meeting.

I’m a participant in a meeting and there is another participant whose camera doesn’t allow her live picture to be been. We followed these chatgpt directions:

Zoom Desktop (Windows / macOS
Start or join the meeting as Host

1. On the bottom toolbar, click Participants
2. The Participants panel opens on the right

Camera controls available to the host:

Stop Video (next to a participant’s name)
→ Immediately turns off that participant’s camera

• More (⋯) next to a participant:
  • Ask to Start Video
  • Stop Video
•  
• Bottom of Participants panel:
  • More ▾
    • ✅ Allow participants to start video (toggle on/off)

👉 If you turn this off, participants cannot turn their cameras on unless you re-enable it.

None of  this worked.  How do we enable a participant to be seen.  She is the only participant blocked.
