A lateral flow test or something using a lab?
Must be a lab test as lateral flow is like £2:

Or $7 in Walmart: https://www.walmart.com/ip/Flowflex-Covid-19-Antigen-Home-Test-1-Test/837992467?classType=VARIANT&athbdg=L1200
I guess there’s a nice idea behind the process. But tbh, I don’t even remember what instance I joined. I tried joining a tech instance but my application was rejected … I’m really not that interested in applying like it’s a job or something. (Though I understand lots of IRL groups have application processes)
