Hello, how do I remove the image that currently is in the social media link preview spot? I want to remove it in hopes that when I share posts from our community into social media sites, the content from the posts is what the preview is.

Right now, the only option to replace the "banner" image with another picture as this section cannot be blank. 

Also, if the link from the community already has a picture in it, when you share the link in other platforms, we show the existing photo. If there is no picture, we replace it with this banner image that you have uploaded in the admin settings> Settings> Banner.
