The same site says virtually nobody, aprox 2-3% is using edge.

You either have to go all the way back to supporting IE11 and ignore everything not supported by 2013 microsoft to capture another shrinking single digit percentage of possible users until they progressively die of old age or ignore Microsoft stuff.

Alternatively start providing a slightly degraded interface with fewer features and a banner. Our website works best with a modern browser with links to up to date edge, firefox, and chrome at top of page. Preferably with a notice regarding dropping support for internet exploder sometime next year.
