For now, I would get it OOW replaced with Apple. It will be expensive but I don't think there are many third party repair shops that are routinely doing micro-soldering on the iPhone X. You may have more luck with some of the big Chinese shops like Rewa or G-Lon so you could always research them.
The iPhone X has a sandwiched pcb design which makes it very challenging to repair. Check out the teardown if your curious.
You can follow the troubleshooting tree here for some other ideas.
Just to note that there are now new tools which greatly improve the success rate of micro-soldering repairs on the iPhone X. My comments were temporal in nature considering the newness of the device at the time.
