At-home kennel cough care

Hi! My one year old lab mix seems to have kennel cough :( it started yesterday, and she was up every hour coughing/gagging overnight. My vet said that since she isn’t vomiting and is still eating, she doesn’t need to get checked out unless her condition worsens or doesn’t get better in the next few days.

I mostly just want to make sure that she’s comfortable over the next few days as she recovers. Are there any at-home remedies anyone recommends? Thank you!
