Unable to "sdb shell" - permission restriction?

I am successfully connected to a QM43C display using sdb over Wifi. I can launch my app but cannot open a remote shell likely due to permission restrictions.
Does anyone know how to enable remote shell support on my device?
See the test sequence below.

Thanks
