How can I return the output of node-fetch as a variable? I would like to be able to call this function and have it return the JSON object.

async function getbody(configType){
    const response = fetch(getURL(configType), {
      method:'GET',
      headers: {
         'Authorization' : `token ${GITHUB_TOKEN}`,
         'Accept' : `application/vnd.github.VERSION.raw+json`,
         'Content-Type': `application/json`
      }})
      
   .then(res => res.json() )
   .then(data => obj = data)
   .catch((err) => console.log(err));

module.exports = async () => {
   getBody(configType)
}
