Share icon

Hi. Has anyone got experience with creating an HTML snippet that shares a page to another site, eg FaceBook, Twitter etc. This is for an education site and I have a Google snippet that they supply that shares the website into Google Classroom Screenshot 2021-02-21 at 13.42.53 . I’ve attached the sort of thing I am after from another edu site.

Just noticed there is exactly the type of thing I am after with a share icon below!! How is this done pls?
