send message from background.js to content.js of another page in chrome extension

Question

I want to send message from background.js to Content.js of Another tab.

Expected flow that I want.

Page1_Content.js --> Background.js --> Page2_Content.js

Is it possible? if yes then how?

A code snippet of background JS.

function sendMessagetoNewTab(tabURL){
      chrome.tabs.query({}, function(tabs) {
      //console.log("sendMessagetoNewTab tabs::::"+JSON.stringify(tabs));
      tabs.forEach(function(entry) {

    if(((entry.pendingUrl===tabURL)||(entry.url===tabURL))){
        console.log("Selected:::"+entry.selected+"::::active:::"+entry.active+":::::forEach tab::::"+JSON.stringify(entry));
    try{
    chrome.tabs.sendMessage(entry.id, {type: "openWindow", xpath: xpath, higlight: true},{},function(message, sender, sendResponse){
        debugger;
        console.log("chrome.tabs.sendMessage sender:::"+JSON.stringify(sender));
        console.log("chrome.tabs.sendMessage message:::"+JSON.stringify(xpath));
        console.log("chrome.tabs.sendMessage sendResponseMain:::"+JSON.stringify(sendResponse));
    });

    }catch(e){
        console.log("Exception::::"+e);
    }
    }
    });
  });
}

function openTabNew(xpath){
    //debugger;

                    var h = 680;
                    var left = (screen.width/1)-(w/1);
                    var top = (screen.height/4)-(h/2);
                    chromeRunTimeId=chrome.runtime.id
                    if(localStorage.getItem("tabId")){
                        chrome.tabs.create({ url: chrome.extension.getURL('landing.html'), active: true }, function(tab) { chrome.windows.create({ tabId: tab.id, type: 'popup', 'width': w, 'height': h, 'left': left, 'top': top, focused: true }) });
                        localStorage.removeItem("tabId");

                    }
                    sendMessagetoNewTab(xpath);

}
chrome.runtime.onMessage.addListener(
    function(message, sender, sendResponse) {
        switch(message.type) { 
            case "openWindow":
