Manage canvas settings in Slack
Canvases are surfaces built into Slack where members can create and share fully formatted content. Channel and direct message (DM) canvases are available on all subscriptions, while standalone canvases are only available on paid subscriptions. Owners and admins can manage access to canvas version history, and turn off canvas update messages for channel and DM canvases.
Manage canvas version history
Anyone with permission to edit a canvas can access its revision history and restore a previous version. If you’d like to, you can disable canvas version history so that only the most recent version is available.

Manage canvas sharing settings
By default, anyone with permission to edit a canvas can grant others access to view or edit it, but you can restrict this so that only the canvas owner can grant access to others. If you don’t restrict this, members of your workspace or Enterprise Grid organisation can choose whether they’d like to restrict sharing on canvases that they create.

Manage canvas update messages
When someone in your workspace or organisation updates a channel or DM canvas, or a canvas in a tab, we’ll send a message to the conversation to help keep other members informed of the changes. You can turn these update messages off, or allow members to manage canvas update messages in individual conversations.
