You can only grant the capabilities for the view template via the grant access dialog. If any of the users you shared with don't have the ability to view the content, the option to grant access will appear automatically after you share.

If you control permissions for the content, you can grant access when you share it. To access the content you share with them, users must have permission to view that content on Tableau Server or Tableau Cloud. Under Message, enter an optional note to your recipients. When you type, names that match your text appear. Under Share with people, enter at least one user name. Open the Actions ( …) menu for the content you want to share.

For more information, see Manage Your Account Settings and Receive Notifications, Search, and Share Using the Tableau App for Slack.

Notifications can come by email, in Tableau’s in-app notifications center, or in the Tableau for Slack app if the site is connected to a Slack workspace. The content is also added to their Shared with Me page, so they can easily find it later. When you share content directly with other users on your site, they receive a notification with a link to that content. For views and metrics, you can also copy code to embed them in a webpage. Share projects, collections, workbooks, views, metrics, data sources, and flows either directly with other users or by copying a link to the content.
