MPG Loop with custom shortcode

Hello,

I’ve created a shortcode function in my functions.php file, and I would like to wall it from a MPG loop, passing it a param, like this :

[mpg project-id="2" unique-rows="no" order-by="my_order" direction="asc" limit="5000"]
[my_custom_shortcode_function link="{{mpg_link}}"]
[/mpg]

The problme is that the shortcode is not interpreted, and instead, this loop displays literraly something like this :

[my_custom_shortcode_function link="https://my-first-link.com"]
[my_custom_shortcode_function link="https://my-second-link.com"]
[my_custom_shortcode_function link="https://my-third-link.com"]
...

Is it possible to make it work, and that my custom shortcode is interpreted within the MPG loop ?

Thanks.
