Return callback variable to main function with Node js

Question

I have a primary function that makes calls from other functions within itself, functions that are called have return with callback as shown in the code below

async function processarFrase(frase) {
  frase = limpezaInicial(frase);
  let fraseOriginal = frase;
  if (frase.match(regexes[0])) {
    let match = await limpeza(frase);
    frase = match;
  }

  getDictionary(frase, dictionary => {
    let grupo = capturarGrupo(fraseOriginal, dictionary);
    console.log(fraseOriginal);
    console.log("Inserir isso no banco, no campo dataset: " + grupo);
    console.log("\n");
  });
}

what needs is that the main function that is the processrFrase returns the variable group because I need to access this variable in another scope, I tried this way below:

async function processarFrase(frase) {
      let group;
      frase = limpezaInicial(frase);
      let fraseOriginal = frase;
      if (frase.match(regexes[0])) {
        let match = await limpeza(frase);
        frase = match;
      }

      getDictionary(frase, dictionary => {
        let grupo = capturarGrupo(fraseOriginal, dictionary);
        console.log(fraseOriginal);
        console.log("Inserir isso no banco, no campo dataset: " + grupo);
        console.log("\n");
        group = grupo;
      });
      return group;
    }

But without success, if I do

 let grupo = processarFrase("Uma frase qualquer");

and give a

console.log(grupo)

the result is

Undefined

how do I so that the main function can return to the group variable?
