Soldering a Seeed XIAO BLE to a PCB using a reflow oven

I have a custom PCB that I’d like to control using a Seeed. To keel the height of the PCB I am currently soldering the Seeed to the pads of the PCB. I also am powering the seeduino through the battery pads on the bottom of it, but this is a cumbersome process. I wanted to know if I could apply solder paste to my PCB and place the Seeed Battery pads on it → Place the device in a reflow oven to solder the Seeed battery pads to the PCB. Would this work or would the reflow oven damage the Seeed as it already has soldered components on it.

My general question is what would happen if I put a Seeed in a reflow oven. Thanks!
