OTA DFU with Seeed XIAO Sense

New to the XIAO Sense but I’ve used the nRF52840 in the past. Has anyone gotten the OTA DFU to work? After setting up, I’ve found the example that puts the XIAO sense into OTA DFU mode. How do you load a new image from there? With the nordic development kit, I was able to generate files and zip to perform DFU all in segger. Arduino is also pretty new to me.
