I need to create a View which displays content of users that their username should be passed as contextual filter. The number of parameters (usernames) are not specified but the View must include every username that is passed via url, as an example

example.com/some-path/user1
example.com/some-path/user1/user2
example.com/some-path/user3/user2/user12

the view must include all of pathes like the above ones and filter the contents but I really have no idea how to implement this using Views UI. I can do this programmatically by looping through each component of the url but I don't want to use such methods.
