type of a TRPC mutation

What is the type of a TRPC mutation if I want to pass it into a component

export default function MyComponent({ myMutation} : {myMutation: ???} {
// mutating things...
}

export default function MyComponent({ myMutation} : {myMutation: ???} {
// mutating things...
}

export default function MyComponent({ myMutation} : {myMutation: ???} {
// mutating things...
}

export default function MyComponent({ myMutation} : {myMutation: ???} {
// mutating things...
}
