Can’t remember screen password

Dear Apple Support:

Please, help me or find the way to remove the screen passcode without erasing my phone. I always used one screen passcode and my face for face ID , this is the secondary iPhone during my trips with all my information. I have some memory issues that’s why I always write my passcodes in my notes and when I needed I can easily check, but this time I’m Having a hard time to locate. Please, help to remove the screen passcode without losing my txt messages and notes , which is very important for me and my family. I can provide with all the necessary information to prove that it’s my iPhone. Please, take my request under consideration and remove screen lock without losing txt messages which I saved since 2019 when purchased the phone . Thank you very much for cooperation.
