Hi @Hannah_Schaub, great to see you in our community, welcome!
I love your idea, it could really boost engagement on a website! You know, we have a similar request for a Comments widget, you can check out it here: Widget for comments - please!
Do you think your request could be merged with that idea, or did you mean anything more specific than just comments and an option to upvote them?
Thanks in advance for the details!
