How to properly notify content scripts about changes in browser extension settings?

Question

JavaScript

There is an extension in which background.js is responsible for storing settings and processing data prepared by the content.js script. Everything works and seems to communicate with each other, but there were problems when writing a script for changing the extension settings.
What is the correct way to inform all tabs on which content.js functions that the settings have changed and that they need to be re-read?
Messages from background.js don't reach tabs.
I tried to send information to all tabs so that they re-read the settings.

chrome.tabs.query({active: false, currentWindow: false}, function(tabs) {
  chrome.tabs.sendMessage(tabs[0].id, {command: "extEvSettingsUpdate"});
});

I understand that the answer may be on the surface, but I do not see it yet.
Especially savvy, please do not send a link to https://developer.chrome.com/extensions.
PS Everything worked. The error is that I used the parameters {active: false, currentWindow: false} when selecting tabs. If empty, all tabs are selected.
Thanks for the hint
working solution: background.js

chrome.tabs.query({}, function(tabs) {
      for (var i = 0; i < tabs.length; i++) {
        chrome.tabs.sendMessage(tabs[i].id, {
          command : "extEvSettingsUpdate"
        });
      }
    });

and content.js from Alexey Yarkov's answer Alexey Yarkov

Answer 1

//content.js

chrome.extension.onMessage.addListener(function(request, sender, callback){
    if (!!request && !!request.command) {
        if (request.command === "extEvSettingsUpdate") {
            // your actions
        }
    }
});
