Connecting ONN Roku TV to wifi without remote.

Several years ago I bought an ONN Roku TV and lost the remote almost immediately. No problem, I just downloaded the app and used that as a remote! No problems at all.

I stopped using the TV for like 2 years. I have a new phone. We just moved.

I was excited to use this TV again, and as soon as I plugged it on I realized....How the **bleep** am I supposed to connect this to my WiFi?
