What is this "On The Fly App" and how do I uninstalll it?

Hello,

I am looking into an issue one of my colleages is having when her Okta token expires way too often (almost hourly). In her logs, I see that she has “User signle sign on to app” events to BOTH “OpenID Connect Client (AppInstance)” and “On The Fly App (AppInstance)” while other colleagues that do not have this problem only has “OpenID Connect Client (AppInstance)”

So now I’m trying to remove whatever app that is this “On The Fly App (AppInstance)” for her. I don’t know what this is, and a search for “Okta on the fly” shows some pages about the Okta browser plugin perhaps.

So do these events indicate that she has some Okta browser plugin/extension installed and that she should remove that plugin/extension?
