Graph API does not support using complex/advanced/deep select.
For example in the Mail Graph API Explorer you can select: from
https://developer.microsoft.com/en-us/graph/graph-explorer?request=me%2Fmessages%3F%24select%3Dfrom&method=GET&version=v1.0&GraphUrl=https://graph.microsoft.com
But you can't go down the tree to get the: from/emailAddress/address
