How to create excerpt for custom post type automatically?

In Newspaper theme, excerpts created automatically, without need to fill an excerpt field.
But on custom post type, I need to manually fill excerpt field. How to do it automatically, same way as it for default post types?

Thanks

I have 3 instances of Flex Block 5. ON two of them excerpt shown by default, as I use there usual posts. On third one, it’s not shown, as I have there custom post types “events”. My custom post type support Excerpt, I just want it to be filled automatically, same way as on default posts.

I’ve created custom post type – ‘edi’. It has: Title,Content Editor,Featured Image,Excerpt.
I created single-edi.php, ant it display the data I enter like here:

Now I want to display it on home page, and I choose on block option post type:

And choose show excerpt:

Result:

Excerpt not shown, only post name, image. IF I fill excerpt field manually, for ‘edi’, it shown as expected.

So question is – how to make it work automatically, as usual posts in theme.

Thanks

Hi, Calin. Can you, please point me, where to set such condition? I use CPT UI plugin, and ACF Pro.

Thanks
