About Trigger.

Using triggers to control slides and use them effectively.

condition
1. After the learner has finished viewing the video, press the Next button to move to the next slide. (Without going over automatically)
2. If the learner has not finished watching the video, how to not use the Seek Bar to complete the slide
3. After the learners have watched the video, how the Seek Bar is only available to the area they have already seen

I want to know number 3 the most among these. But if possible, I want you to tell me all three ways.

Triggers are usually only possible with one action. For example, user click, after a while, is it impossible to set up duplicates? I need a redundant trigger function, for example, after time has elapsed and then I use the Next button to move to the next slide.

I'd appreciate it if you could tell me the above method.

Thank you.
