Forgot security pattern to unlock admin profile in infotainment system.

At the initial setup of the admin profile for my 2023 GMC Sierra, I went with the security pattern option and made my mobile phone and trusted device. Aside from some Bluetooth issues it worked okay until there was a problem with the My GMC app crashing for 2 days. When I was finally able to access the app I discovered that my mobile phone was no longer a trusted device and that I could not get access to the infotainment system. I had used my phone as a trusted device for so long that I had forgotten the pattern I had used. I spoke to a couple of people with OnStar and all they could offer was to set up a new user profile and disregard the admin profile. This is not a good fix. Although I can use some of the features, many of the permissions granted to the admin are lost. This was not allow me to manage other user profiles and I am essentially a teen driver with limited capabilities. There has got to be a way to reset the infotainment system to factory settings whereas an admin profile can be set up again, or some backdoor in the programming that would give one access to an existing admin profile. I understand that there are security concerns for everyone who owns a GM vehicle, but there has to be some mechanism built in to reset everything. I assume that this is not a singular issue. I'd like to have the full functionality of my truck. Can someone please help!
