Hello @connyduck!

Thanks for your contribution! I will try my best to check the pull request this week.

BTW: May I ask how did you find this issue? Are you working with Kentico Kontent and Android?

[connyduck]

We use the kontent delivery library in our Spring Boot backend and we have custom elements in our project.

@connyduck - are you willing to take a look at some notes I have noted above? I am willing to take a look at it and finish the feature, but I can't promise you a fixed date.

Your changes look OK and I am willing to merge the pull request and keep the issue open with the notes I have added above.

@Simply007 I think I addressed everything Not sure why the CI is failing though

[Simply007]

Let me check the CI.

I have removed the unused step that was failing (I am currently using a different approach to publish the versions).

I will take a look at the changes - but from my brief check, the changes look awesome @connyduck! Thanks for that :)

Is there any specific date you would like to have the functionality out? 🙂

No, but the sooner, the better of course!

Released in v4.3.0. Thanks, @connyduck - one of the smoothest cooperation lately.

I am about to mention this pull request in the upcoming Kentico Developer Flash!
