I believe the answer is currently no, but is there a way to do impersonate mode with ApliqoUX? If not, can we request that this feature is added? I use impersonate mode a lot for testing in Arc, and I just noticed the latest release of TM1py (1.6) includes options for impersonate mode. It would be nice to have this same capability for testing ApliqoUX interfaces.
The answer is currently no but it is on the roadmap for exactly the use case you mention. When the report builder is in the admin group it is a nice feature to be able to test a screen as the end user to make sure that there are no missing security permissions which prevent things from working.
I may stand to be corrected by @tganz but I think the timeline is probably for the May 2021 release.
Nice! I took a screenshot just in case!
