How to check Firefox/Chrome developer console/tools on Android without a computer?

Question

I am aware of these two questions

However the first one is interested in Opera and that is not the browser I use for development.

As for the second one, there is some interesting answers, however my goal is to see the console only using a mobile Android device (Redmi Note 9S).

Sorry, I posted an app answer and deleted because I was told that app does not provide the console functionality. F12|Browser console for Android Devices was the app — beeshyams, Dec 31, 2020 at 13:53

That feature seems to be unavailable for all major android browsers. You could try Opera-mini instead.

Reset the console output by opening a new tab with the address debug:resetconsole
Open a tab on the page on which you want to do the inspection:
Run JavaScript code on the page by replacing the address in the address bar with the following address javascript:var%20n%3Ddocument.firstChild%3Bwhile%28n%20%26%26%20n.nodeType%21%3DNode.ELEMENT_NODE%29%20n%3Dn.nextSibling%3Bconsole.log%28n.outerHTML%29%3B
Retrieve the output by opening a new tab with the address debug:console
