using these versions
"@onflow/fcl": "^1.4.0-alpha.8",
"@onflow/typedefs": "^1.1.0-alpha.4",

const sign = await fcl.currentUser.signUserMessage(MSG);
// types think that signUserMessage returns a CompositeSignature` and is not an array

// but in reality it is an array
const [{ signature }] = sign;
