Type an incoming function

How would I Type this incoming function prop for this React Hook Componet? Right now I just put any which is bad but I don't know how to type it, I'm new to TS:

const FeaturedCompanies = (findFeaturedCompanies: any) => {
...
}

It's just a plain function:

async function findFeaturedCompanies(): Promise<Array<Company>> {
  const response = await fetchFeaturedCompanies(),
    ...
}

Since findFeaturedCompanies returns Promise<Array<Company>>, just type the function as one which returns that:

const FeaturedCompanies = (
  findFeaturedCompanies: () => Promise<Array<Company>>
) => {

If findFeaturedCompanies happens to be in scope of the FeaturedCompanies declaration, you could also do

const FeaturedCompanies = (
  findFeaturedCompanies: typeof findFeaturedCompanies
) => {
