In this exercise and at the end of the squeze I can see the scapula moving away from thw spine, around the thoracik cage.
What muscle effects this particular movement of the scapula?
Is it Serratus Anterior?

I'm no expert but I think the scapula is just moving because it's attached to the shoulder. The only muscle doing any work is the pecs. If you want to work the seratus, do these.

When the shoulder is abducted and forearm is at a 90 degree angle as shown for pec major isolation the infraspinatous and teres minor (which originate at the posterior scapular surface and attach to the posterior humerus) are contracted to componsate the anterior muscle action (pecs). As the elbows move toward that midline, the infraspinatous and teres minor engage and the rhomboids relax causing the scapula to shift laterally (abduction)

Sorry if it got to wordy
