Need a trigger on a video integrated into a 360 ° picture

Hello,
I attached a video to a marker embedded in a 360 ° picture.
I need to integrate a trigger which changes the state of all markers to inactive, when I click on a marker containing a video.
I need to integrate another trigger on the video which changes the state of the markers to normal when the video has been viewed or when the video starts playing.
Here is my problem: I have several markers positioned in a 360 ° picture. A video is attached to each marker. I need each video to be watched before going to the next slide. However, currently, the learner just needs to click on each marker, without looking at the attached video, to move on to the next slide.
