Airdrop and continuity

I have a intel dual band wireless ac 8260 wifi card and intel wireless bluetooth card.

Please let me know if continuity features and airdrop are possible on these at all.

I looked through the sub and online guides but couldn't find anything concrete about airdrop, sidecar and universal display support on Intel wifi and bluetooth cards. The guides say they are fully unsupported and only broadcom ones are supported but I've seen posts claiming these features work on their intel cards (given not reliably).
