use web-interface on android < 9.0

I have used the asana app on a tablet running android 8.1. It now requires android 9.0 so it will no longer run.
if I try to access asana via browser, all i get is the “download app” button (chrome, firefox).
Is there a way to use asana on android < 9.0 devices?
If so, could someone please tell me how?
thank you in advance.
