Video Schema Embed Error

Hello,

I have recently enabled video embed schema using your plugin.

I have entered both Url’s.

Vide Content Url: https://youtube.googleapis.com/v/B9W6SyqHxXg
&
Video Embed Url: https://www.youtube.com/embed/B9W6SyqHxXg

I published the page but checking the schema tester tool, it Looks like that only contentUrl is showing up: No Embed Url.

https://search.google.com/structured-data/testing-tool/u/0/#url=https%3A%2F%2Fwowbix.com%2Fimportance-of-digital-marketing%2F

Can you please help me on this? I have checked it on different pages as well, but embed url is not showing up on the tester.

Thank You
