Snaphu import via Graph builder/GPT

When we run Snaphu import from the dialogs in SNAP GUI there are options to select wrapped phase product, unwrapped phase, etc.
Like so:

But, in Graph builder there is no field for supplying input paramaters.

I’m interested to make a graph that starts by reading unwrapped phase (with Snaphu import) and then doing some other operations.
But not sure how to set it up, because there are no input/read options that I can supply to the snaphu import node in Graph builder.

I am wondering if I might need to put 2 regular read nodes before the snaphu import node, and let those read nodes read the wrapped and unwrapped phase respectively. But if so, how to connect them in the graph?

Any advice on this?
