Disable Laravel debugger

I have a Laravel application that was not developed by me. There is some weird bar at the bottom of each page, it is some type of Laravel debugger tool.

I believe it is stored in storage/debugger. Is there a safe way I can go about checking to see if this is actually it and if so can I delete this type of tool without it affecting the application? Does anybody know what this thing is if so any advice on how to remove this safely would be greatly appreciated.

Thank you.

I had searched online and I had seen most of solution are related to.env file. But I am unable to find.env file in code.
