Idea by @uditaren from the Telegram Chat:
Use resistors with a wire diameter of 0.35mm. Those fit right into the vias beside the tag connector debug connection. Be sure that there are no shorts!
You can use a 0 ohm resistor or just clip off the wire of your resistor. Depending on the female jumper wires it may fit directly or like mine you may push it through the bracket hole of it.
You can get the GND from the antenna connector. (The second image is also an example how you could connect the wire to a jumper cable)
