嵌入式签名后重定向下载文档页面

I am using embedded signing with PHP as there on DocuSignAPI embedded signing session redirect url

When i am redirecting signer to Signing URL. After signing the Signer is redirected to Return URL. Instead i want signer to redirect to Docusign Page with Download Document button. enter image description here

Also the signer is not getting mails with the signed document.

Is it possible in Sandbox mode?

I have done settings in Admin panel for sending mails after signing enter image description here

In embedded signing, it is NOT possible for the signer to be redirected to Docusign Page with Download Document button.

Alternatively, you can redirect the Signer to your APP and create a page with the "Download Document" button. Upon clicking the button your app can call the getEnvelopeDocuments api and download the document.

Make sure your app authenticates the signer.
