We know the slope of the profile on yellow cam and the needed displacement of the gray pin, so we can calculate the position of the gray pin on the blue fixed part.
Due to the kinematic pairs between the blue fixed part, pink follower and gray pin, the pink follower should be move with the gray pin in the horizontal direction simultaneously.

In this video, I set the pink follower to move in the cycloidal curve motion in the horizontal direction while the yellow cam is moving in the constant velocity.

Dimensions: 90 * 28 * 25.6 (mm^3)
Input Stroke: 50 mm
Output curve: Cycloidal curve 50 mm，without dwell
Contact plane clearance: 0.15 mm
