Inviting someone who play on Switch

[rastafunrise]

I was wondering how can invite someone who plays on Switch to join my squad or duo. They connected their Epic and Switch account and I have them as friends on Epic but that doesn't seem to help. Also tried to search for their username and I find ppl from Steam, Epic, Playstation and Xbox but not Switch.

Did you searched from Epic Games Name or from the Nintendo Name.
If you want to add someone as a friend be sure to be on the first tab on the Social Panel (The second tab is for accepting or denying friend requests and not sending them from there)
