@Deep the link you shared is for embedded dashboards. I am asking explicitly for non-embedded dashboards where users access dashboard directly from aws console.
If you don’t want embedding thats fine and you may ignore that section. However. befor that section, the solutions is done within the Quick suite console only.
Content before “Create parametric headers and titles for visuals for use in an embedded dashboard” is on DATA. My post is on JUST changing visual elements e.g. Title, Sheet name.
