How do I remove this neutral/reverse connector from the gearbox?

hi there are two connectors I need to unplug. one came off easily because there is a tab you press down. this other one has no tab, there is nothing to press to separate it. i don't know if this is the reverse or neutral one. does anyone know how to disconnect it? cheers !

some of them you slot a small flat head screwdriver and twist/pry it to lift a tab, rather than a push down tab
thanks mate, where would the flat head go though? there doesn't seem to be a slot or anything except for the part where it fits onto that little metal bracket to the left.
