2021 T@B 320S Cabinet Removal

I know there is a thread, and I've read it regarding the removal of the cabinets from the back. I attempted to remove mine and wanted to as much as possible retain the quality of the bottom shelf and doors in case I wanted to replace them at a later date. After removing all the screws, it seemed as though there was someway that the front of the shelf was affixed to speaker cabinet that I couldn't figure out. Seems almost like a tongue and grove and you might have to make a cut. Any help appreciated.
