When you generate a custom_post_type in responsive lightbox it is not set to show in rest by default. This is a one-line change at around line 1100 of your code when you register the CPT, can you add this into a future release?
I saw your request and I think I am facing the same problem right now. You wrote that it is solved with only one code line. Would you like to share your solution with me?
I just created a request with my problem description. If the setting of my website helps you further:

Best regards and thank you in advance!
