Any online research opportunities that are free? (International student)

Anything in the field of stem or even econ atp, just want to do some assistance work or any position that is available. Found a few 'research' opportunities on insta but all of them seem like scams (discord moderation does NOT count as research!)

I have a lack of ecas related to my major: BSC Physics or Aerospace Engineering (other than some local competitions) mainly cause its almost non existent in my country.
