JST connector of the RFD 868ux got removed. How to correct?

The JST connector of my RFD 868ux air module got removed. I thought of just soldering it back BUT two of the soldering pads (serving RX and TX) also got removed.

I thought the soldering pads at the back of the JST connector might help out. But can’t find their assignments anywhere in the datasheet (https://files.rfdesign.com.au/Files/documents/RFD900ux%20DataSheet%20v1.2.pdf)

If anyone can help out, that will be great.

PS:- New to this, please tell if I can post this issue any differently.
