Remote control app in phone or additional device for iPad Pro to primarily use for volume & mute on iPad when not within arm’s reach

I’m just curious if there is any way to control the iPad volume without having to physically touch the iPad Pro. If a person has disabilities it’s very understandable that this could be a bit of a challenge despite it seeming like a simple thing to do.

I seem to recall that the original iPad 1 actually DID have a compatible remote that came with it or was an accessory that could be purchased.

I understand that the iPad does not have an infrared eye or work on any of that sort of technology. It does however work with WiFi & Bluetooth & part of a network of devices. So I don’t think it’s an absurd question to ask under the mobility challenged circumstances.

Thank you so much for your consideration!!
