Disney+: How does Solus do the trick?

Sstteeffaan

Officially, the Disney+ streaming website does not support Linux.
There are contradicting news if it works or not, but it seems to have to do with DRM.
The good news is: It works w/ Firefox on Solus.
I'd like to run it from my Raspberry Pi, though, and there I get the infamous error 83.

My question now is: How does Solus accomplish that streaming in the browser works for Disney+?

Thanks

Sstteeffaan Probably the widevine plugin that Firefox supports. Raspberry Pi is ARM based so they might only support it on x86. Looks like Disney fixed this last December: https://www.omgubuntu.co.uk/2019/12/disney-plus-linux-support-fixed
