What do types of markers do?
Adobe glossary seems to be quite brief and not saying anything about these types of markers. As well as most of Youtube videos that never cover them. There are 5 types of markers here. And I've got several questions about them:

1) What is the difference between Comment, Chapter and Segmentation markers? When you chose one of them only the label color automatically changes, and the only difference is that the Comment marker has a comment text box, whilst the other two don't.

So why should I use Chapter and Segmentation markers if I can just use the Comment marker and don't type anything in the comment section? Why are there Chapter and Segmentation markers if you can just create one of them and change the color yourself?

2) What's the Web Link for? What is the Frame target - what should I type there? Why is there a separate marker for a web link if you can just type the link in the Comment Marker text box if you need it?

3) What is the Flash Cue Point, what is it for? If it concerns the flash animation, then why is it still in Premiere Pro if Adobe flash was abandoned in 2020 or somewhere near.

What are these Event and Navigation types for, what do they do and what should one type in the Value text box?
Thank you.
And please be more technical, I'm not a baby
