You need to TLS intercept the traffic, downgrade it from HTTP/2 and then insert a header. There are instructions at https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/app-id/http-header-insertion/http-header-i...

Indeed, historically this is accomplished through HTTP header insertion described above. 

 

An alternative method would be the new SaaS Security Inline subscription, some of my customers opt for the latter as it's much easier to configure and manage.

Guys thanks for the reply.

I not getting your solution please explain in details.

@BPry  Do you have any idea about this?

@DavidWalters2 's answer covers it in detail. If you click the link you will see next to the header value:

 

 

You can allow access to specific Google accounts from your domain. The values that you give to this header are your domain and subdomains.
 
To successfully insert headers for Google applications, you must also:

 

  • Create an SSL decryption profile that includes the following categories and URLs:
  • business-and-economy
  • computer-and-internet-info
  • content-delivery-networks
  • internet-communications-and-telephony
  • low-risk
  • online-storage-and-backup
  • search-engine
  • web-based-email
  • drive.google.com
  • *.google.com
  • *.googleusercontent.com
  • *.gstatic.com

 

 

HTTP header insertion is not currently supported for HTTP/2. To insert headers, downgrade HTTP/2 connections to HTTP/1.1 using the Strip ALPN feature in the appropriate decryption profile. For more information, see App-ID and HTTP/2 Inspection.
 
Create rules to block the Quick UDP Internet Connections (QUIC) App-ID and place them at the top of your security policy because the firewall does not support header insertion for this protocol. When you do, the app reverts to using HTTP/2 over TLS, which the firewall handles in the previous step.
 
So you'll need an SSL decryption profile (guide here), you will enable the "Strip ALPN" feature in the profile you create. You will then create a decryption policy on the above categories, also a block QUIC policy. Lastly, you will follow these steps to add the google header value to the sessions.
