The domains that you want to add to the allow list for access to the generated URL that is then embedded. This
optional parameter overrides the static domains that are configured in the Manage QuickSight menu in the Amazon
QuickSight console. Instead, it allows only the domains that you include in this parameter. You can list up to
three domains or subdomains in each API call.
</p>
<p>
To include all subdomains under a specific domain to the allow list, use <code>*</code>. For example,
<code>https://*.sapp.amazon.com</code> includes all subdomains under <code>https://sapp.amazon.com</code>.
