Trigger event by Marked Frame in Sequencer

Hi Folks. A doubt.
How do I Trigger event by Marked Frame position or Frame number?

For example I have a similar case, I put a button that when clicking directs the sequencer to that marked frame.

I’ve tried other things, but when I do a test to find a marked frame, it just returns that yes, it has that marked frame.

It would be like this, when the sequencer arrives at the frame with a specific marked frame, the condition would validate the branch that would activate the event. (or something similar)

Thanks
