Unable to add android native apps in UiPath Mobile Device Manager

Hi, I’m trying to add android app in mobile device manager (MDM) but not able to do the same as [Save & Close] button is not there in the MDM window. But for Web option, the button is present and I added web browser and its running fine. Can anybody help me on the same?

I’m using UiPath Studio Pro 2020.4.3 Community edition. I’m not sure whether this is a licensing issue or not.

Thanks in advance !!
