i need help to remove the external link that appears on the top right corner on the chart on my google site. i am working on a google site and i want to create a dashboard using excel sheets chart. i had to embed my charts on the google site but there is always the external link icon on the corner that gives every visitor to the site to open the chart on a new tab. i want to know how can i remove it. This icon does not appear if i embed a picture or video it only appears on my imbedded charts and my site doesn’t look nice on a mobile device. Please i need help to remove it.

I have tried to research and i couldn’t find any answer on my research. i was hoping to find answer from developers and youtubers.
