Requesting access
If someone opens a link to a private file, they do not hit a dead end. They see a request-access screen. The owner gets a notification, approves or declines, and the requester is let in with view rights, the same flow you know from Figma or Google Docs.
Inviting teammates
For people you work with regularly, invites beat links: workspace members see every project, while project invites scope access to a single project. Invited teammates can edit, comment and generate; link viewers can look and, once signed in, comment. Roles and the invite flow are covered in Workspaces, people and roles.





Pin comments on the canvas
Feedback works best next to the thing it is about. With the comment tool C, click anywhere on the canvas to pin a comment to that exact spot: a specific image, a material, a corner of a render. Replies thread under the pin, so discussions stay organized.
Type @ and a name. They get notified and can jump straight to your pin.
For annotations that should stay part of the canvas rather than a discussion, use a note instead; the difference is covered in Notes next to the work. And for the whole client review workflow built on these pieces, see How to collect client feedback.
