Devtools detect is open

Hallo liebe User Gemeinde, ich habe eine Frage. Kann ich mit JavaScript / jQuery o.ä. auslesen, ob jemand ein von mir eingebettetes Video (per Videoelement) bis zum Schluss geschaut hat? Wenn ja, wie? Hat jemand eine Idee / einen Ansatz für mich? Vielen lieben Dank.

Der hier verwendete Code
