TSphinxExternalProvider.IconUrl Property
Optional URL of an icon to display next to the provider name on its "Login with..." button.
Remarks
The value is used as-is as the src of an img element, so it may point to a .png, .jpg or .svg file. An absolute URL (starting with http://, https://, // or /) is used verbatim; any other (relative) value is resolved against the login app root. Sphinx ships built-in icons for the most common providers, e.g.
img/providers/google.svg, img/providers/microsoft.svg, img/providers/github.svg, img/providers/apple.svg and img/providers/facebook.svg.
