We want to move our GTM tagging agent from Copilot Studio to Mark.

The agent would talk through tagging requirements with the user, create a named workspace, build the tags and sandboxed JavaScript templates, and send back a preview link. Our team reviews and publishes every change. These gaps stop us:

• Create workspace: name and description, using workspaces.create, so each request gets its own workspace to review
• Custom templates: create, list, get, and update sandboxed JavaScript templates
• Workspace preview link: a shareable link so users can test changes without edit access to GTM
• Update tools: update existing tags, triggers, and variables, and delete variables
• Admin controls: limit an instance to approved containers, and stop agents from creating versions or publishing
• Workspace status: show conflicts and changes before review
