How to share internet under official SD-WAN Site to site connection?

I have two MT1300, one works as Main node while another works as Node 1. I have completed the setup by using official Goodcloud “Site To Site” SD-WAN service. I can now access both local network. My question is: Can devices connected to Node 1 surfing internet through the Main Node under official SD-WAN service?

I know I could setup through Wireguard / OpenVPN Server and client myself. But I would like to use throught official SD-WAN for better online routers management. I have read other similar threads but still cannot find a solution.

Not be able to do it now. I understand this is the requirement of a lot of users.

We will improve this later.
