I think that might depend on when the feature was first added. If SB/SV had it before they switched to XF2, the addon they used might be available and work. If they only added it after they switched to XF2, then it won't work and will just have to wait until we have XF2.
(Personally, I dodge the whole issue by turning off like alerts altogether.)
Is there like. A centralized thread for status updates on this, or something? This has been "in the pipeline" since before COVID shutdown, as I recall. If it's just been quietly abandoned, that would also be nice to know, for example.
