I agree with many others, this is not completed as requested. Adding a SharePoint library is not the same as having the Teams part of an existing site; rather it creates another site. This should be an option: Create new site or be part of an existing site.
This feature is on the backlog. I will update you when we have more details to share.
Adding any emoji as a reaction remains under review.
I am marking this as partially done to let you know a new reactions bar with Like, Heart, Laugh, Surprised, Sad, and Angry has begun rolling out to all users.
