Odoo 13.0 Can't see my installed module on the menu

I am a newbie on Odoo 13.0 (and any Odoo version). I just built my first module, and successfully installed it. The problem is that I can't see my installed module on the menu. I have tried restarting the server and also I have researched these sources but anything seems to work for me:

Here are my files, so hopefully, someone could point me out in the right direction.

Edit: Here is the image of the menu, I was expecting to see my sample_test application in there after installation.

Also, Odoo shows my installed app here:

I appreciate your time and help in the matter. Thanks!!

Solution

I just found how to do it. These are the steps I followed to solve my problem:

As shown in the image, I don't have the School module on my menu.

So, I went to Settings and Activated the Developer Mode (First one)

Then after the page was reloaded, my main bar (not sure about the actual name of it) turned into this:

I noticed that a bug appeared in my main bar

Then for the sake of curiosity, I clicked on the bug and selected the option Become superuser

I noticed that my main bar changed like this:

Finally, after opening the Menu my module was there!! (hooray!)

And, that is the end for the story (for now) I still need to figure out how to deploy this changes into production, but that my friends is another story!

Thanks!
