Upload file to Rocket Chat https://docs.rocket.chat/api/rest-api/methods/rooms/upload#example-call

Here is an example

curl "http://localhost:3000/api/v1/rooms.upload/GENERAL" \
    -F file=@$HOME/example.txt \
    -F "msg=This is a message with a file" \
    -F "description=Simple text file" \
    -H "X-Auth-Token: ijFlJ1yfidXhwEYY284Anoq_iEsOeMMVCupzNhX22tB" \
    -H "X-User-Id: hw5DThnhQmxDWnavu"

How can I implement in HttpRequest node?
I’m taking the file from IMAP node attachment.
