That would be the correct answer. However, there are open source alternatives, which can be worked on to get to and passed their level of integration and implementation. Anbox being one example.

I am seriously considering of getting the device I was planning to test out the device at their office if/once they organise that. In which case I would work on an android app compatibility layer be it Anbox or something else.

Speaking of Anbox, by default the keyboard is disabled as it is set up for use on a desktop/laptop. This device would not have that issue, making one less thing to fix.
