Route SSL VPN Client connections to WAN specific public IP without "Use as Default Gateway" option enabled

Dear all,

1. We have a subscription on Microsoft Azure and we allowed our headquarter public ip on Azure firewall to permit to connect to it.
2. I have a mobile consultant that is connecting to our headquarter throught an ssl vpn connetion with dedicated profile.

I need to route requests from the consultant's device to Azure public ip throught VPN tunnel so that it can use our headquarter public ip, but XG deny the connection.
To do this, I added a local route with the Azure public IP pointing to vpn gateway on consultant's device, I created a "network rule" to allow the traffic masquerading its vpn private IP with our public ip.
I see the request on XG firewall but it deny the connection.
I tried also to add the Azure public IP in the "Permitted Network Resources" in vpn config profile without luck.

If I enable the "Use as Default Gateway" option it works, but I can't force all its connection throught the tunnel.

Thanks in advance.
