Cannot find Logitech Setpoint for Android

[MsJazzMaven]

I just bought a Logitech K810 Bluetooth keyboard to use with my LG Stylo 2, running Nougat 7.0. Everything works but the "Caps Lock" light and onscreen notification. I would also like to customize the F2 and F3 keys for media controls and monitor its battery. Searching online has been unsuccessful. You'd think Logitech would have ported it over by now. Android wasn't born yesterday. Where else can I find software that would unlock these functions? I looked on Google Play and all they had from the manufacturer were apps specific for their other devices, a virtual keyboard, which I do not need and an app for switching languages. Logitech seems not to reply to messages. Where/what else can I try?
