As a user I want to share the content in the Experience Cloud community over social media. primarily over Facebook, LinkedIn, Twitter. It will help me share articles and topics discussed in the community in my network.
Icons like these may help on top and bottom of an article may help.

Though currently there's an option to share the community content over social media via "Add this" widget. But, the icons are small in the right hand side of the page.
If the option to share is available under the topic heading and with sizes similar to the user avatars. It will be easier for users.
