Hello Andrea Franzoso
Thanks for contacting us. You can override Property Details view on the template. For example, you can create this directory:
templates/your_template_name/html/com_spproperty/property/default.php
Then add your customization to the default.php
file. This design will be used to show Property Details page. It will not be changed even if you update SP Property component.
There is no editing option on the admin panel where you can include shortcode. But you can use shortcode in the default.php
file. One thing I would like mention that you can only design this one file and it will be shown on all property details page. So, all property details page will have the same shortcode loaded. Unfortunately, we do not provide customization support and can't help you further in this regard.
Best regards
