Mouse & Keyboard for IPad Mini/ Pro 9.7 Inch

Hello, forum!

I have an IPad Mini and a Pro 9.7 inch. I’m a tech reviewer in my country(România) and I don’t like to write on the virtual keyboard from the iPad/IPhone because, it’s very uncomfortable for me. So, I want to my a keyboard and a mouse/trackpad or a keyboard with trackpad, I don’t know.

I need a mouse/trackpad because my iPad is connected to a monitor via HDMI adaptor and a I can’t scroll on my device screen.

I already found some keyboard models, but no mouse models.

Keyboard & Mouse budget: 70$( or 100$)

Keyboards models that I found:

-Logitech k480, black: https://www.bestbuy.com/site/logitech-k480-bluetooth-multidevice-keyboard/920110 4.p?skuId=9201104

-Anker Ultra Slim: https://www.amazon.com/gp/aw/d/B00PIMIUPW/ref=dp_ob_neva_mobile#immersive-view_1 518252912171

But I have a problem! I don’t found mice compatible with my IPads, that’s a really problem! Does exists a Bluetooth mouse for merci ? Or a keyboard with trackpad? I have a lighting-USB adaptor, if I will buy a wireless mouse with USB interface, will it work?

Thank you.
