Hiding Widget when sequencer is off

I`ve been looking through some posts about hiding widgets, but my case is a little bit different.

I need the widget to get visible when my sequencer take starts, keep visible even when it’s paused, and disappears when the sequencer ends or get stopped. Someone knows how to solve this?

Can you use IsPlaying on the SequencePlayer? Or Bind Events OnPlay/OnPause/OnStop?

I’ve tried the IsPlaying, but I don’t know where or how to plug it`s output (Create Widget > Add to Viewport > Get Visible). I have tried some things, but all randomly, with no success.

How would be this Bind Events? Do you have some example?
