Content creation

I am not able to get my camera or microphone to work in Chrome and in Firefox, while I can get my camera and microphone to work, I do not get an active room.  Any ideas?

Can I call the SUMMARY something else (it is in the interactive  videos). I want to call it 'short quiz' instead of 'summary' - but I cannot see where I can change it...?

Hi everyone, I want to create a new content from external data (for example with drag text content type and data from an excel file). Who can help me or show me suggestion? Pleaseee

I have read source code of H5p plugin but I don't understand all. I find insertContent() function in public/class-h5p-wordpress.php and I tried with data created but it only insert data to wp_h5p_contents table, don't insert data to wp_h5p_contents_libraries => content type in a post doesn't work

And I find some function in admin/class-h5p-content-admin.php file but i don't know how to do
