I am modifying my embed-content.php. I find the functions here to remove some oembed icons but not the share icon. I do not find a function to remove JUST the share icon on wordpress oembeds. Can anyone help?

From the answer to that question:
Here's the code to remove the site icon markup from embeds:
add_filter('get_site_icon_url','__return_false', 10, 3);
If you want to remove the entire site-icon + site-title then use this:
The right thing to do though would be to upload your own site-icon in the WordPress customizer and show-off your branding. Min image size it needs is 512px.
