How to make dialouge in a cutscene

I am trying to make dialogue boxes appear in level sequence. I want be able to allow the boxes to stay there until player input advances to the next line. I tried following some advice I’ve seen to pause the sequence when dialogue appears. But once i figured out how to pause don’t know what to do next.

I made an actor that has a collission box with overlap event which runs the play and pause, and i use a dialogue component i made for npcs and used it here to display the dialogue with a sequence event. But after i pause the sequence, not the game but the sequence, no matter what button I use I can’t get the sequence to unpause.

This is essentially the “go to next line” function i have for my dialogue component

I use a interaction interface to make dialouge appear on npcs, with sphere trace

I’m still new to unreal engine, so i really don’t know much. I was also inspired by this video which did help me with the pausing but nothing else works https://www.youtube.com/watch?v=Spt0t0Z8cvU

Also even when unpaused I can’t get the dialogue to advance. I’m not looking to use any plugins at the moment I wanted to try out making my own system for my specific needs. If anyone knows what to do please help.
