Dialog cards

Hello, I need you to guide me because I have not been able to solve the issue, I have investigated in documents and not found the answer, I am working on localhost, to present content, I have all the h5p plugins that I found installed in moodle, and when I do the activity and I try to call it to show it, I get this error, can someone tell me what happens? I would like to generate content without using the iframe of h5p.org but something more native to the platform, is there any way or it depends on the server and iframes external, thank you!

Moodle 3.9.6+

I am wondering if a new content type could be created by adapting the features of existing content types, 'dialog cards' and 'match the words'

I work with a First Nations school in Canada, where the Nation's language, Hul'q'umín'um' is taught.  Many First Nations schools in Canada teach their Nations language. 

While teaching, an effort is made to only use the Hul'q'umín'um' language.

A couple of features I would like to pay to develop on existing Content Types.

1. For the Dialog Cards conetnt type I would like to remove the Turn button for certain sets of cards that do not have a back side.

2. For the Image Pair content type I would like to have an option to randomize the matches and only display X number at time (similar to how Memory Game works when you set "Number of cards to use.")

Where can I find paid developers to help with customizations like this?
