Help with switch

Hi sorry if this answer is obvious, recently my little sister discovered jackbox games and she loves them a lot more than I thought she would so she plays with me (we have a switch lite) but often she wants to play with more people (more games available for more players) like her long distance bf or my brother in FL. Is there a cord or way I could get the screen onto something like discord? We have to basically video chat using a different device and there’s games that make it tricky if you can’t see what’s going on so I was hoping someone would know. Thank you!
