Hi All. I'm migrating existing AWS infra to pulumi, and need to replace parts gradually. Is there a way get an Instance of some resource that already exists outside Pulumi? e.g. I want to create an

aws.sns.TopicSubscription

to a topic that already exists, but the topic param must be a

pulumi.Input<Topic>

- so I need an instance of

Topic

first.

new aws.sns.Topic(...)

will try create a new topic with a unique name, which is not what I need.
