Iframe Custom Visual

Hi everyone,

I'm currently developing a custom visual that aims to display a HTML Iframe.

When I'm developing it in Service, it works properly (the webapp hosted in my company cloud is loaded and displayed and I can interact with).

But since I package the visual and trying to use it either in Desktop or either in Service it doesn't work. I've an error like "This content is blocked. Contact the site owner to fix the issue."

Have you ever experienced something like that and have you found a solution, or any ideas? 

For those that are interested, the code is here:
EquinetPaul/powerbi-visuals-iframe: powerbi-visuals-iframe (github.com)
The only thing to change are the privileges in capabilities

Then you can go to formatting pane and put the URL that is related to the domain you autorised in the privileges

Thanks in advance for you answers !
