And I have one other quesiton:
Does Electrum alreadu supports the p2tr addresses or it's still too soon?
It is planned, but not implemented yet:

Yes, naturally we plan to add taproot support.
Initially only singlesig wallets with keypath spends will be implemented.
To be able to create watch-only versions of these wallets (required before we can expose it to users), some wallet-refactoring and wizard changes are needed, as we don't want to extend the current x/y/zpub scheme. Most likely some form of output script descriptors should be used.
No ETA, but it is on the TODO list.
