Data transfer from Andriod to iOS after setup

So this morning I got a new iPhone SE 3rd Gen and set it up. I meant for it to be an upgrade from my current Galaxy S10. No less than 30 minutes ago I finally downloaded Move to iOS on my Galaxy and tried to start a data transfer, and when it didn't work, I did a little bit of digging and found that Move to iOS is only designed to transfer the data during the phone's setup, and I had already set it up. Is anybody aware of a way to do the data transfer in my current condition without doing a full reboot of the iPhone?
