I do importing my old diary entries into Apple Jounal app via "Create Entry" action.

The action has "Media items" field. I tried to pass in it Base64 encoded images or images from "Get images" action without any success. I could find only one way how to put valid images there - via "Select photos" action but it's not an option for batching entries importing (( The only difference of "Select photos" is its value "Photo media" type (unlike "Get images" and "Base64 encoded images" - they have simple Image type)

The question is how to create an instance of "Photo media" type not selecting a pictures manually? Currently I have JSON file with all my exported diary entries and it's simple to add additional "image" field to each entry for importing. But how to correct pass base 64 encoded image data from the field to "Media Items" field of Journal "Create Entry" action?
