Can't Install a Basic Plugin

Hello,

I am following this tutorial in Elgg 5.0 https://learn.elgg.org/en/stable/tutorials/blog.html 

and I am able to activate the plugin, but the plug in does not show up on the website nor does it show up in the settings page,

nor do I get any error....

 

Did someone come with the following issue...

Is there some other tutorial for designing apps in Elgg 5.0
