Ich habe versucht, dem Facebook App-Link ein Thumbnail hinzuzufügen, kann aber keine Dokumentation darüber finden. Ist es möglich? Der aktuelle Code (PHP/Laravel) gibt mir einen funktionierenden Link, der so aussieht: https: // fb.me/1234567890. Es schreibt den App-Namen auch bei Facebook, aber ohne Bild/Thumbnail. Ich habe versucht, einen "Bild" oder "thumbnail" -Parameter in http_build_query zu setzen, aber ohne Glück.Das Thumbnail/Bild kann nicht zu Facebook hinzugefügt werden App-Link
