Support mice in app feature for iPad Pro

I’m not asking a question, but a feature request.

Maybe apple guys already had this thought, if the engineering can consider to support apple mouse in app feature.

because some apps like browser, MS excel, MS word, etc indeed need a mice where it can bring much more productivity to the iPad and make the iPad a real productivity tools.

if you agree with me, let’s make apple aware and support it.

Thanks.
