Hi @Yanice KABEL,
As said in this article: Sharing options are greyed out when sharing from SharePoint Online or OneDrive,
- Note The Anyone with the link option might be greyed out if you attempt to share .aspx pages. Sharing .aspx pages is not supported.
Unlike files or folders, pages are not allowed to be shared with "Anyone" in SharePoint Online. It is an expected behavior. SharePoint online pages are mainly used for internal team collaboration rather than for the public.
Hope my answer helps. Thanks.
