For your reference: Play a video full screen
Regarding to, “Also, how do enable a play button to play this inserted video? “As your inserted video button in a PowerPoint slide is different than mine, may I know which video format you inserted into PowerPoint slide? also please confirm are you insert online video or video file from pc into your PowerPoint slide.
