Operators without xuid?

I want to setup a server for my kids but when they login there is no xuid in the log. They don't have mojang accounts, just a local profile in the app. I want them to be operator in the server when they login. What can i do?

The issue mentions local profiles, missing XUIDs, and operator access, but names no repository file or test. Start by determining how the Bedrock server identifies local-profile users and grants operator permissions; done would require a clearly documented, supported path for making these users operators.
