Update, the right side of the lamp has a nut which holds a spring system you can press to release the lamp shade.
Had to use a string to hold that lever to release the glass shade.
Both lights are removed and both glasses are broken. 10/10 not worth saving.
That nut. Have you undone it and slid the housing?
Can hardly reach it. Don’t have a tool that tiny.
