It just happed I've recently launch this wallet.

Here you can see true Taproot K of N multisig.

You can test it on TestNet

I use Multy spending paths (address and script) with Huffman TapTrees, so you could have a 2 of 100 multisg and pay very little of transaction fee and only reveals the 2 public keys of the 2 signatures, the other 96 address are NEVER revealed.
