Connecting a disabled iPhone to a Wi-Fi network

Good day you all.

Some days ago my iPhone xr fell and I picked it up I saw that the touch screen has started touching and typing on it's own. So I decided to shut it down and then turn it on again but after booting up the phone started typing wrong pass codes on it's own so I angry like locked the screen and kept it in my drawer. Then later when I tried to check it to see if its stable, I was that the photo has been disabled that I should connect to itunes.

Now I've managed to erase it via find my phone but it says phone will only be wiped after I haven't connected it to a Wi-Fi network. Now my question is how can I connect my disabled iPhone to a Wi-Fi network? Please guys hello me.
