Watch strap release button

Hi all

Got a Google pixel watch and unfortunately the watch strap caught on my rucksack strap, which ripped the strap out of its holding, as a result, the release button on one side has come off, unfortunately I don’t have the button, is there anyway, you guys can be repaired, or to replace the actual outer casing, I’ve looked everywhere but can’t find a replacement outer casing.
