defineEmit in composition API and typecast it properly in my composable

I define an emit in my <script setup lang="ts"> and I want to send that emit to my composable to actually do the emitting for me.

However, I do need to cast my received parameter to something (because any is obviously not very nice and unknown doesn't think emit is a function)

I have the below code:

export type EmitType = {
    'search': [value: string]
}

And I initialize the composable with something like this:

<script setup lang="ts">
const emit = defineEmits<EmitType>();

useComposable(emit);
</script>

I then use EmitType to cast my emit parameter

const useMyComposable(emit: EmitType) {
  emit('search', 'a string');
}

By doing the above my emit() in the composable gives the error:

This expression is not callable.
  Type 'EmitType' has no call signatures.

Which I understand because defineEmits most likely has a different type.

So in short my question is:
How can I properly define emit in my composable to be error-free, not use any as a type and have the proper intellisense?

I think this should do the trick. As your typescript error said, your previous type was not callable. This is.

type EmitType = {
    (event: "search", value: string): void;
};

const emit = defineEmits<EmitType>();

const runEmit = (emit: EmitType) => {
    emit("search", "string");
};
