Hey there @Andy33, I hope you're having a good start to your week!
The best way to do this would be to use a shared folder, which you can share to everyone who needs access to the folder.
With a shared folder, you can see any changes that the others have made within the folder and vice versa.
I wouldn't recommend sharing an account itself, as this is against our terms of service.
I hope this helps, let me know if you have any questions!
