iPhone X Problem with backup

[Lexio]

Hello, I have a question. Today I have changed my battery in my iPhone with ios 13. They have erased all my content and all my settings. When I came back i started to backup my phone, but it installed ios 12 so I cannot install my ios 13 backup. Do you guys know how I can get this backup on my device?

Reinstall iOS 13 and then restore from backup

Download public beta profile, install iOS 13, erase the phone again, and restore from backup.
