Auth proxy for non-standalone backends like crypt/combine/union

It seems that return result of an auth proxy script is not enough to specify a non-standalone rclone backend. For example,

[encrypted]
type = crypt
remote = remote:/Encrypted

we need to have a config entry for the remote backend before we can create a crypt backend.

welcome to the forum,

not sure what you need help with?

create a remote named remote
