How to automate actions or steps performed in WMS Cloud RF web-based for regression testing ?

Summary: As part of regression testing efforts, business is looking into automating the testing process using an application like UiPath and is facing issues as per attached screenshot since the web version of the RF handheld is identified as a single page application. It is not possible to automate selecting specific menu options or elements on the screen. They managed to do this in the UI web based application but not for the RF. Do you have any direction or recommended approach to do this ?
Also, can you please confirm what coding language is used for RF application development ?
Thank you.
