What else do I need to stream?

So, I'd like to stream on Twitch using the Switch.
A laptop is available, a capture card, the switch with all cables, microphone, webcam and a monitor. Do i need anything else?

Internet.

Obs or Streamlabs. MIGHT BE SOMETHING a streamdeck.

paypal or something for due donations

Twitch Studio

Streaming software, obs or something. Otherwise I don't think anything.

Definitely a good internet connection and a platform with which you can stream; like OBS.

Otherwise that sounds good, Lg.
