Question Showing modal messages from extensions?

[Almamu]

Hello everyone, I'm developing a Plesk extension and I was wondering if there is any PHP-side function to output a modal message's html (asking for user input, or pressing yes/no buttons) to be triggered by a link or do I need to write all the html by myself (for example looking at one of the plesk modal's html and replicating it, thing that would be really bad if you update the html for those modals...)?

Thanks in advance
