Run Extension in Background in photoshop

[waqasa29715664]

HI Adobe Community. 
I have developed an extension where images remain on screen (visible) for a given amount of time. But i want to have the controls on brush and layers (ideally on all photoshop options) to draw that image, which is visible for a given time. 

But the problem i am facing is that once i start the extension, it disable any photoshop option (brush, layers etc etc).

So can we somehow use the extension in backgroud and have the photoshop running in full capacity.

What exactly do you mean by »extension«?

If I understand correctly CEP has been on the way out for a while now, so you might be better off with UXP.
