Can I publish an App to manage the Galaxy Fit 3 spheres?

Xiaomi’s smartbands are also based on FreeRTOS, like the Galaxy Fit 3. There is a separate app to upload created watchFaces to the smartBand, following the FreeRTOS API requirements on GitHub.

My question is, ¿can I create an app to manage Fit.3 watchFaces and publish it on the Galaxy Store?

Could someone tell me if I make this app and publish it on the Galaxy Store, will I have problems or not?

The first requirement is that you have a commercial account with DUNS number that allows you to sell apps on the Galaxy Store?

I have the D.U.N.S number and the account activated. But my question is whether I can publish an APP to manage watchFaces from my mobile.
