How to change the brand description

We are using the menu item type (Posts) Frontpage at the following URL:

https://ippl.info/library-news

I am trying to figure out how to change the text "This is some blog description about this site". Also, is it possible to get get the category description to display on this page?

I then created a menu item type (Categories) Single Category at the following URL:

https://ippl.info/library-news-2

This displays the category title and description, but since we would like to use the Frontpage menu item because we want the category name to display above the toolbar.

Also, in the (Categories) Single Category menu item, on the Category tab there are options for show category title and show category description, and "Inherit from default settings". Can you tell me where in the EasyBlog configuration I can change these?

Thank you.
