Mac os is current v10.15.7 but Zoom needs v11.0?

[Wallace300]

Hi! I uploaded and installed Zoom v6.0.2 from their website on my mac os 10.15.7 twice now, but when i try to open it, it tells me that it needs os 11.0 or later to work with Zoom v 6.0.2, so is there another Zoom version that will work? When I trying to update my os it says that it's current?
