Using Chromium Edge you just need to have install the properly Micro Focus UFT agent. It should be downloaded from here: https://microsoftedge.microsoft.com/addons/detail/pmapbmihblakhgodloklimjbaoohkiop
It works using the only the UFT agent such as IE, Chrome or Mozilla Firefox.

But if you need to use Edge browser, it needs to follow a different process, including the webdriver mentioned in our official documentation: https://admhelp.microfocus.com/uft/en/15.0-15.0.1/UFT_Help/Content/Addins_Guide/Edge_Extension_Setup.htm

Important: Please keep in mind that at this moment UFT has support to Chromium Edge version 79 and version 80. (https://admhelp.microfocus.com/documents/uft/PAM/UFT_15.X_PAM.html#Chromium%20Edge)
