Projector on transparent ground doesnt show in pass through

[amtsamy]

Hello i am trying to implement a shadow using a projector but the shadow does't appear in Passthrough mode, i saw i found a shader that you can put on the ground to show real time shadow, but i didn't find anything to show projecotr image.

According to the details here:

..the decal renderer doesn't work on transparent surfaces which I am guessing passthrough is...?
