Considering Moving to Teams

We're a two person non-profit shop with me using mostly Lightroom and some Photoshop and my associate using Photoshop, InDesign, and some Illustrator.  My associate also serves another client.

I want us to share my Lightroom CC library and it seems like Teams is a great way to do this.  

• If I join us through Teams what are the downsides?
• Can I easily move her to Teams and will she get access to my Lightroom CC library along with my folder and album library organization?
• I want her to be able to keep her work for her other client away from me?
• What if there's some kind of problem I've not thought of, can I separate us without me losing control of my photo library?
• What have I not thought of?

Thanks!!!
