Probably not.
Mouse support for iPads did not appear until iPadOS 13.
So, no.
There is NO mice or trackpad support for your nearly 8-1/2 year old iPad model running a 4-year old iOS 10 operating system.
Your iPad is too old.
Sorry.
If you need/want an iPad with up to date features, like mouse and trackpad support, with access to current, updated apps, then you really need to seriously consider a new iPad model OR a much, MUCH “newer” and less expensive, used iPad models, from better known, trusted Apple product/device retailers/resellers, capable of running the latest iPadOS versions.
There are plenty of newer, older iPad models that can run the latest, current versions of iPadOS.
Sorry & Best of Luck to You!
