Which joy-con pins can I cover with tape to prevent connecting to switch (but keep charging)

[elmnt61]

So, the right side of my switch has water damage which prevents it from making a "wired" connection to a joy-con. (The joy-con is seen as connected via bluetooth even if it's loaded on the rail.)

BUT, it still charges just fine.... I tried cleaning the contacts, opening my switch....

So, in order to play handheld mode, I need to find a way to do the same thing to the left joy con (otherwise games don't recognize my combo wired/wireless joy cons.)

I know there are 10 pins in the joy-con that communicate with the switch. Can someone tell me where to place some tape (or PLEASE suggest a better idea) to cover the "wired" connection but maintain its ability to charge? thank you!

Found some data here :

So if 1 and 4 make contact, it should charge in theory.
The rest is the same GND or signals.
