How do i get parts to push against each other?

I'am new to Onshape en new to 3d CAD. I have a simple mechanism. The grey part slides over the blue part (slide mate) and the purple parts rotates around the axle. How do I get the purple part to rotate when it interacts with the grey part?
The geometry of grey and purple need to be refined, for now that's not relevant.

There are come clever ways to fake it, but Onshape does not do collision detection.
I'm not sure I fully understand the result you're after, but if you add small fillets, you might be able to get what you want with a tangent mate.
As @Matt_Shields said, Onshape doesn't do collision detection.

Fake it could be a solution. Any idea How?
I would like to use this to refine de geometry.
I've had limited success with the tangent mate.

@Matt_Shields to do any more you would probably need to create a guide curve that controls the path of the pink actuator.
Also, a different (more complex) approach is to use the animator custom feature to generate the guide curves:
