How to create a fixed bottom menu?

[puddinpops]

Hello friends, I use Wordpress and what I want to do is have a fixed bottom menu on mobile. I'm talking about the ones found in mobile applications. For example > [https://klasresim.com/i/oGhEy](https://klasresim.com/i/oGhEy) There are a few plugins available to achieve this, but they don't quite match what I want. I would be happy if it could be done. I added a new menu from the Wordpress original menu creation section. Now, how can we configure the position of this menu at the bottom of the site? There are a few resources online about adding positions, but I can't do it myself since I lack coding knowledge. For example > [https://codex.wordpress.org/Navigation_Menus](https://codex.wordpress.org/Navigation_Menus)
