iPad Pro M1 11 inch not connecting to external display via HDMI

I have an iPad Pro M1 11 inch. I am using a USB C Hub which supports DP Alt Mode. I am trying to connect an external display to my iPad via HDMI. The display is not getting detected and hence the iPad display is not mirrored. The volume bar in the control center changes to a projector bar for a second and then changes back to the volume bar. The USB C hub is working perfectly fine with a laptop and even with Samsung phones (Dex).

Running the latest iPadOS 16.5.1 (c)

Is there a way out of this ? I have tried 3 different USB C Hubs already and none of them seem to be working. Anyone else facing a similar problem ?
