Forcing user to view slide until the end in Storyline 3

Hello. I've got hundreds of slides to publish and I need an easy way to ensure each slide is viewed until the audio is completed. Under the old Articulate version there was a player setting where I could do this in one click/player. I now have 11 different modules totally about 500 slides so I'd love to know if there's a simple way to ensure each slide is viewed to the end.

The other setting requirements are: 1) seek bar is read only, 2) forward and backward buttons.

I'm new to triggers so I think the solution lies there.

Is there a player setting that will do this?

If not, is there a way I add a trigger to all slides at once?

If not, is there an order in which the triggers have to be placed?

Any and all help appreciated.
