I have a problem with returning my functions in js. Basicly Im calling a function in a js file and need to return something that is stored in chrome.storage extension, as seen in the script. This is very easy to achive as i thought, until it wasnt. This script i have doesnt work and returns undefined. Please help me, how do i return the correct thing?

Script:

function getSettings(){
    chrome.storage.sync.get(["grade", "gradeStyle", "finalColor"],(res)=>{
        return res
    })
}
export {getSettings};
