iPhone unavailable try after 3 hours

There is an Apple article that explains what to do if you have forgotten an iPhone or iPad passcode. Click on the following link: If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support

If that option is not available, you will need to use a computer. See: If you forgot your iPhone passcode - Apple Support

Did you get a resolution to this? My message and circumstances are the same. I was just working in the garden with my iPhone Xin my pocket while I listened to a few podcasts. Took it out and this ******** message is on the phone and I can’t do anything it’s the phone.
