Toy / Gadget Battery Compartment Lid Removal

Hi All,

Couldn't figure out correct forum to post this so hopefully this one is OK 😀

Has anybody here ever come across a battery compartment lid like this (see attachment) in a toy / gadget? As well as the screw there's a kinda spring-based release mechanism as you can see. The screw doesn't fully unscrew (at a certain stage, it just turns but doesn't loosen any further) so some wizardry required with d release mechanism and a flat headed screwdriver apparently but can't figure it out. Nothing online either. Strange one. The instruction video simply has about 2 seconds of somebody unscrewing with the Philips screwdriver then releasing the spring-based release mechanism with flathead but it ain't that easy for me. Thanks in advance for any suggestions...
