Gstreamer from Raspberry Pi to OpenCV C++ on PC

Dear all,
Uisng a PI Zero 2W, I send a gstreamer pipe to my PC through Wifi.
When I set the gstreamer pipe on the PC to get the video feed, it works fine.

The receiver: gst-launch-1.0 -v tcpclientsrc host=X.X.X.X port=5000 ! decodebin ! autovideosink
So this pipe works and I would like to know how to setup Opencv 4.7.0 (C++) to add this pipe to get back the stream.
Thank you for your help and support.
Best regards,
