alert well enough or to eventually add some additional descriptions to only be seen by the screen readers in order to grant the page's accessibility.

Together with links and basic HTML tags like strong for example the alert elements in Bootstrap 4 can also include Headings and paragraphs for the cases when you would like to present a bit longer content.
