Hello.
If you have already connected AWS and on-premises with DirectConnect, you can communicate by connecting on-premises and Azure with Express Route and setting the appropriate routing.
Alternatively, you can configure AWS and Azure to interconnect using services that support multi-cloud connectivity, such as Megaport.
I think the following documents will be helpful.

Thanks Riku for the feedback! can you please suggest with any example reference for setting the appropriate routing.( Example ip route 10.x.x. 255.255.255.240 <AWS_DirectConnect_Next_Hop_IP> ip route 172x.x.x 255.255.255.240 <Azure_ExpressRoute_Next_Hop_IP>) Is my understanding correct ?
Yes, I think your understanding is correct. In order to route with an on-premises router, a route to AWS VPC and a route to Azure must be configured.
Agree here. I have aws connected to azure in several locations but that’s via S2S vpn over the internet. If you want to connect DX and Express route you need a 3rd party to connect the 2 either via on premises or via a multi cloud communication company such as Riku has mentioned or Equinix who can connect both providers together.
