How to upgrade the macOS to Mojave or Catalina from High Sierra

I have a MacBook Air (2013), currently running macOS High Sierra Version 10.13.6 and would like to upgrade to Mojave (10.14) or Catalina (10.15). The AppStore is only showing the option to upgrade to Big Sur (11), however I am concerned about upgrading to Big Sur because my computer is old and it will most probably significantly reduce its performance. I would appreciate you advise / comments.
