So, with collaboration, u can start a facetime call and ask if others have ideas. If others have ideas like in safari u can accept the invite to view the changes he or she made. And the other people can join the tab group too so everyone can see what is going on. All these will work with Collaboration. With the new Free forum board, your team can brainstorm new ideas to better your project. This new way of sharing ideas is coming in the fall time. Free forum is being built into IOS, macOS, & iPadOS.
