Minecraft Bedrock Realms Monitoring Tools

I own a mine craft bedrock realm and am having troubles with theft. I have several friend groups, who don't mingle in real life, in this realm and people often have there stuff go missing. There is no way for me to monitor the realm because there are no tools for it. It would be cool to have the option and it warn players or something like "hay this realm is now monitored by the owner don't rob peoples chest"

To be more specific on what I'm thinking:

A menu that shows all player movement within a day to a week. You just click on the player and it shows their coordinates for that week and from there you can see what they have done. As well as being able to see the coordinates of any chests they have interacted with.
