zoom workplace on iPad

[EddieSYD]

The iPad version of Zoom does not have a volume setting within Zoom, what do you do?
With the ability to connect an external camera, the volume seems to be dependent on Ringer.
Even if the volume of the iPad is set to maximum before starting Zoom, Low Power Mode and focus mode are deactivated, and in addition, the volume is set to maximum after starting Zoom, there are times when the other party's voice cannot be heard.
Has anyone else experienced the same phenomenon?
