Cross-Post Type Connections

Hi,
Automatically displaying related posts is not possible. However, we have an option called manual post selection. Screenshot – https://ibb.co/WyD5GQY

You can enable this option and then edit a post. From the sidebar, you can handpick the related posts you want to display. Here is a screenshot for reference – https://ibb.co/8Ym7YgT

thanks for replay. These options works without gutemberg also?

Sure, it will work.
