Can I transfer documents from the files app on iPhone to my new Android phone?

I’ve already tried to use google drive to do so, but for some reason only empty folders get transferred. I’m switching to a Oneplus so the Galaxy Smart Switch app (which I had used to go iOS to Android once) is not compatible. I have a usb-c to lightning cable and have tried Wondershare MobileTrans which i guess no longer allows cable to cable transfer between ios and android? Please help it has been a week since my frustration.
