integrate a webapp from github in a wix webpage

The idea is that people goes in to the website, buy a zoom session where we will discuss the results given by that app. On the day of the session the app is displayed on the website, we both can see it as this runs in a subframe or something inside the website, and then I interpret the results in the zoom session with the customer.

I found a couple of webapps already available in github that can accomplish this purpose, I just need the one we select to be integrated with the Wix website.

I will design the Wixwebsite and all the needed functionality, the one and only thing I need is to integrate the webapp inside the flow. As detailed above.

Im also open to suggestions about the best way to integrate them in a working website where people can book a session with me to work around the results of the webapp (without Wix)

Im considering using this, of all the ones I have explored, is the best so far https://www.wix.com/scheduling-software

And so the webapp would need to run inside Wix, un a subframe or something inside the website

Again, I will do everything, all I need is for you to help me run the webapp inside the Wix environment

This is the webapp I have in mind https://nphollon.github.io/iching/
