How to modify content in notification dropdown window (Buddypress)

Hi, I`d like to modify a text content in the notification dropdown window of Buddypress notification generated from a determinated plugin.
For example, I use the following plugin:
https://buddydev.com/plugins/bp-notify-post-author-blog-comment/
It send a notification in the admin bar to the post author when an user do a comment in a post. The structure of the notification is the following:
USER X commented on TITLE OF THE POST: CONTENT OF THE COMMENT
In this case the CONTENT OF THE COMMENT showed in the "notification dropdown window" is very very large (a lot of text...).
When user is connected from computer, it is no a problem.
But when user is connected from mobile device the very large CONTENT OF THE COMMENT is annoying.
So my question is:
Is possible dont show the he content of the comment included also the ": "
: CONTENT OF COMMENT
when user are connected from mobile device?
I`d like use the following CSS:

@media screen and (max-width:782px) {
¿¿¿¿CODE???
    }

Is it possible using CSS to establish how show a notification created from a specific plugin? (in my case the plugin is: https://buddydev.com/plugins/bp-notify-post-author-blog-comment/).
If it is possible, please add the code for the plugin I have add. Please dont post an "example code" because I am not informatic and I dont understand of CSS.
Thanks for your support.
