Post grid widget - How to include all custom post types ?

[Samoreen]

Hi,

I have a Post Grid widget on a page and I want the grid to include all available CPTs which will be filtered by the user by using the Elementor Super Cat filter bar (a thingy that is available for the Portfolio widget but not for Post Grids, nobody knows why). The Source field of the Post Grid widget correctly displays all CPTs but doesn't allow to select multiple CPTs.

How can I fix this ?

Thanks in advance.
