Set iframe Permissions on App Extensions

Hey there,

I wonder if it is possibly to adjust the iframe policy of a Custom Panel of an App Extension. I would like to use the navigator.clipboard.writeText functionality as described here (Unblocking clipboard access  |  Articles  |  web.dev) within the site displayed in the iframe. For that an iframe attribute allow=”clipboard-write” is required to be set, as you can see here

<iframe
    src="index.html"
    allow="clipboard-write"
>
</iframe>

Is there any option to do so from the Pipedrive App Settings/Permissions/Developer-Hub site?

Thank you and best regards,

Gökhan
