I've been searching for an extension to mute (not block) ads on platforms. The following lines are from a script intended to do that on Spotify, but the remute section doesn't work; I tried to use the setSeconds() method after setting it up, but that also failed. Code from GitHub:

var addTitleText = "Spotify";

function checkTabs(tabId, changeInfo, tab) {
    if(tab.url.includes(spotifyUrl) && tab.audible){
        var actionExecuted = false;
        console.log("Inspect Spotify tab change.", tab.title);
        if(tab.title.includes(addTitleText)){
            if(!tab.mutedInfo.muted){
                chrome.tabs.update(tab.id, {muted: true});
                console.log("SOUND OFF");
            }
            actionExecuted = true;
        }
        if(!actionExecuted){            
            chrome.tabs.query({url: "https://open.spotify.com/*"}, function(tabs) {
              chrome.tabs.sendMessage(tabs[0].id, {action: "getSource"}, function(response) {
                checkAnotherAds(response, tabs[0]);
              });
            }); 
        }
    }
};

function checkAnotherAds(source, checkedTab){
    if(source.includes("control-button--disabled")){
        if(!checkedTab.mutedInfo.muted){
            chrome.tabs.update(checkedTab.id, {muted: true});
            console.log("SOUND OFF");
        }
    }else if(source.includes("control-button")){
        if(checkedTab.mutedInfo.muted){
            chrome.tabs.update(checkedTab.id, {muted: false});
            console.log("SOUND ON");
        }
    }
}

async function start() {
    chrome.tabs.onUpdated.addListener(checkTabs);       
}
start();

Any suggestions?
