How to host in viewport a third party windows (like by windows handle)

Hi everyone,

I’m a newby with UE5 and I search a solution to host another window into the viewport during the runtime. The idea is pretty much simple, for my application need to use another window with some information and this work like a charm when you use UE on classical display BUT when you want to use an helmet (VR) you can’t seen the other window with very useful data.

So, it’s possible with the window handle of the third-party application inject this one into the viewport during the runtime (for the VR) at a specific position of FOV ?

Thank you in advance for your time !
