Does anyone know how to implement favicon?

Hi mate! there's a problem on my site on google side. Im using ip domain for my site like x.x.x.x , and it already indexed by google and showed on page 1 on google search.

but unfortunately there's no favicon showed on my site on google page result, i already generate the favicon code using realfavicongenerator site. here's my code :

this is the code of my favicon on html:

<link rel="apple-touch-icon" sizes="180x180" href="apple-touch-icon.png">

<link rel="icon" type="image/png" sizes="32x32" href="favicon-32x32.png">

<link rel="icon" type="image/png" sizes="16x16" href="favicon-16x16.png">

<link rel="manifest" href="site.webmanifest">

<meta name="msapplication-TileColor" content="#da532c">

<meta name="theme-color" content="#ffffff">

anyone who can give me a solution to solve it and succeed until the favicon showed on the google search page result will be rewared $50 (using paypal). thank you!

Does this work for you?
