p2tr – Error making a Taproot descriptor with a single key as script path

I have to implement 1 of two multisig with P2TR.

My pal’s Bitcoin public secret’s 0374d5f29bc6c15066437856c512f7f9e5a14a1eb93cab2776d33b27b4103c62d8.
My very own Bitcoin public secret’s 035d107216d89a540edacba2bc6719f3a9c6eac538bebac8b305e8cd42c3e466ae/

I’ll use my public key because the Key Path and my pal’s as script path.

Can anyone inform me how one can create a P2TR descriptor?

I acquired following errors:

./bitcoin-cli -testnet -rpcwallet=w_p2tr getdescriptorinfo "tr([0d378869/44'/1'/0'/0/1]035d107216d89a540edacba2bc6719f3a9c6eac538bebac8b305e8cd42c3e466ae, [(0xC0, [0374d5f29bc6c15066437856c512f7f9e5a14a1eb93cab2776d33b27b4103c62d8, OP_CHECKSIG])]"

AND:

BUT I acquired the descriptor proper for key base solely:
