I've purchased a number of these ESP32-S3 modules from AliExpress.

I want to use an external antenna, and have purchased a few, but I can't figure out how to use the u.FL antenna instead of the PCB antenna. It's not like other boards I've seen where there is a clear spot to move the resistor to. I suspect that I need to move the little resistor from its current position to the spot highlighted in red. Does that sound about right? Anyone else have experience with these?
