Add string into a list and remove the text in the search bar of a SearchInput / textinput

Question

Lets say I have a searchInput from shinyWidgets or regular textinput from Shiny on my app.

I want the user to able to write something, press enter - the code adds that into a list. Such that search_1 ENTER, search_2 ENTER, search_3 ENTER

That searchinput UI shall be reset everytime enter is hit.

Output needs to be "search_1, search_2, search_3"

I have workaround for now, with searchInput splits the input text with ", " so the user needs to type "search_1, search_2, search_3" themselves, which is not optimal for the use.

Hope could this be done? Thanks in advance!
