Getting Talk Widget active academic theme

I’m having difficulty getting a widget working with the hugo academic theme.

the website is here: and the files are here:

I have slides here

But I cannot for the life of me get a “talk” widget to work. I have a .md file for some information included in the “content/talk” folder, and I build the site. The config.toml file has a widget added in the main menu, as instructed, #talk. There is a menu button to that effect but it’s not active.

I hope I’ve provided enough information here.
