[Outreachy Task Submission] No Success or Confirmation message on adding a new Collection

[kivenalaric]

Enhancement
To me i believe a user should get like a Message after creating or adding a new collection letting him or her know their collection has been added. But this doesn't happen on my jokima deployment after adding a collection.

Is your feature request related to a problem? Please describe.
A confirmation message clears the users doubt so he or she wont have to go checking available collections to be sure they are there cuz after i add i go and check to be sure cuz just a refresh happens.

Describe the solution you'd like
A simple pop up box should display for about 3 seconds after creating or adding a new collection.

Additional context
screen record of event
