LinkedIn feed with Elementor

Hi there,

nothing is shown.

Console shows:
The script has an unsupported MIME type (‘text/html’).

This is the called URL, which is working without embedding in elementor.
https://widget.tagembed.com/63986

I integrated the Widget via elementor and placed it into elementor html element like described in your docs.

Would you please have any hints for me?

Thank you!

with best regards,
chris
