UE 5.3 Eye Tracking on fixed camera view

Hello,

my goal is to use the eye tracking on my htc vive xr elite while viewing through a fixed camera view with blueprints as follows:

For eye tracking i use the blueprints as in this link and it works: Eye tracking | Varjo for developers

The problem is when i activate Set View Target with Blend or possess a camera. Then the eye tracking doesnt work anymore. Is there a way that both work together?

Thank you in advance!
