broken keyboard and lost plastic bracket

hello! a few months ago i accidentally popped off my down arrow key from the keyboard. i couldn't get the plastic bracket nor the actual key back on. i ignored if for a few months but it's been irritating me a lot since i can barely use that key now... but my actual problem is that i LOST the plastic bracket (i still have the key though), what can i do now? i don't have an apple store near me and i need my computer so i can't send it away to get it repaired either. is there some type of replacement brackets i can buy - and if so is there a specific one i should get or can i just get anything?

i have macbook air M1 2020 if that helps.
