To disable or enable text selection across the entire page, simply add the respective actions in a workflow.

To disable text selection for a specific element, follow these steps:

1. Go to Settings > General > Enable the option "Expose the option to add an ID attribute to HTML elements" at the bottom of the page.

2. Add an ID Attribute to the 'text' element for which you want to disable selection. The "ID Attribute" field is the last one in the "Appearance" tab within the element editor (Any text that is unique to this element will work. E.g., "disableSelection123").

3. Add the action "Disable/Enable text selection by ID" in workflows, providing the ID Attribute of the element.
