How to extract multiple email addresses in a Google doc?

This is the content of the cell and several like this. I need to extract only the email addresses.

This is the function that I have so far:

=arrayformula(regexextract(query(split( transpose(split(A1, ",")), ":" ),"select Col2 where Col1 contains 'email'",0),"\w.+\w"))

I have more than one cell with the info when I applied this function I am not able to drag down the function.
