Transferring books from iPad to Kobo

Hey guys! So bear with me, I’m a bit of a noob when it comes to electronics. I’ve searched for the answer online but couldn’t find it.

So I used someone’s iPad Pro and with a USB-C to USB hub, I was able to connect my Kobo, download books on the iPad, and transfer them from the Folder app to my Kobo by just dragging them, as the iPad recognized my kobo as a device.

I have an older iPad (7th Gen) so I’m not sure if it’ll work or not

Thanks so much!
