Good morning,

That is a great question! You can share that document to any of your teams by using the share dialog. There are a few ways to get to that sharing dialog. From the document list, you can click on the “more options” (the three little dots), and selecting “Share”. From there just start typing the name of the team, and select the team you’d like to share the document to. See my screenshots below for reference.

In addition, you can use the share button in the upper right hand corner of the document itself, and in the share dialog follow the same steps of typing in the name of the team you’d like to share the document to. 

I hope this helps!
