[Suggestion] Allows ES to add the Twitch video showcase without the Twitch link on profile description

[Rysanlos]

Hello, I saw ES have this feature to add a video showcase on the profile when we are streaming on Twitch if we have the Twitch link on the profile description.
But I don't want to put the link on my profile description, is it possible to also read the link directly on the infobox showcase?
Thank you
