Youtube-related javascript files are detected by Google Page Speed Insights but I can not find them on the website

I have job board built with webflow. The homepage takes a long time to load. This became more apparent recently.

When I check the google page speed tool, it shows some strange results. It says:

“Reduce the impact of third-party code Third-party code blocked the main thread for 5,310 ms”

Then when I expand the 3rd party is YouTube. Some examples of .js files found are: https://www.youtube.com/s/player/c9dd45ed/player_ias.vflset/nl_NL/base.js and https://www.youtube.com/s/player/c9dd45ed/www-embed-player.vflset/www-embed-player.js

Looks like js code used for embeds, no? But the problem is, I do not think I have any embedded videos in my job posts. There could be, but I can not find them with search. I also can not find them when I check the page source. Or when I crawl my website with a technical SEO tool like Ahrefs and then used their advanced search features to check the entire website source.

What do you suggest I do to fix this? The website is https://remoteineurope.com/

I think the big load times were caused by a cloudflare workers script. I turned that off and the page load is better in the browser, though the google page speed report is the same. So I would still like to find out where the youtube .js files are coming from exactly.

Somebody helped via DM. The key was to search the page source for the term <iframe not youtube
