I forgot the Google account after formatting in Huawei MediaPad T3 7,

After I formatted the Huawei MediaPad T3 7, I got a FRP lock and asked me for the old email associated with the device, and I forgot it. I tried the method where "Add Network" appeared, but I didn't see "Share", only "Cut" and "Copy". How do we bypass the protection and return to serving the tablet without a Google account? We like an effective method in detail, preferably without a computer.
