Loose thing inside my phone

There are three golden pins. I suspect it is the one near the Wi-Fi/Bluetooth module:

Repairing a Librem 5 Modem

It is possible to remove the antenna connectors using just the fingernails, like I did when I replaced my Redpine module with the SparkLAN module, but it requires great finesse and patience. The antenna connectors themselves can also last past 10 removals, as I learned when disassembling the Librem 5 multiple times. I had more trouble keeping those three golden pins in place when putting everything back together.
