VidzFlow; Text is not showing when placed over Vidzflow video

I have a webflow background video placed on my webpage with a heading, paragraph and a button placed over the video. The video will not autoplay, so I am trying VidzFlow. When I place the heading and paragraph over the Vidzflow, the text will not show. Has anyone done this successfully?

I want to upgrade to a paid Vidzflow plan when i can work this out.
