Force users to watch full 90-minute video

We recorded a training on Teams and now want to put the recording into ALM. We have added the 90-minute video into Captivate. We can turn the playbar off, which prevents people from fast-forwarding through the content. But, the slide duration is only 3 seconds and it maxes out at 600 seconds, which means people can leave the training and it will be marked as complete. What needs to be done so people are forced to watch the entire video?
