Amazfit Watch faces

I'm wondering if we could make watch faces for Amazfit Band 5 when it comes out, or if it already is out. If there are Mi Band 5 Watchfaces, then it should be possible to make faces for the Amazfit Band 5.

Preferably something like https://amazfitwatchfaces.com/editor/watchfaceEditor/.

Also, Are there any tutorials for the tool you provide? Or does it work with JSON? I don't know.

Are there any tools for making Mi Band 5 Watchfaces on macOS? (Catalina)
