Hey @Lecoqdigital,
I’m sorry but the instruction provided in the documentation are quite general or not specific. I’m also not familiar with the Panorama plugin so I’m not the best person to help you with this. What you will need is someone who has experience customizing the Panorama plugin and also X and Pro. We do not have such a person here and as you might already know, third party integration is beyond the scope of our support.
Here’s a section in our Terms that is related to this case.
###THIRD PARTY PLUGINS
Customers are certainly welcome to extend the functionality of their site with the use of third party plugins, however our policy is that unless they are integrated into the theme in some way or explicitly listed as supported (Extensions), then we can not provide support or guarantee compatibility. The implementation, customization, and troubleshooting of any issues that may arise are the responsibility of each customer. Technically speaking, since our products developed according to development best practices, any well developed third party plugin should play nicely, however due to the virtually limitless nature of things that can and often times do go wrong with software, we can’t support something that we have not first developed or integrated into the theme. For plugins that are integrated into the theme, support covers product related questions (no customizations).
I understand that this is disappointing but I hope you’ll also understand our side. Third party integration is a premium service which we currently don’t offer.
Thank you for understanding.
