Increment number while getting object from fauna db?

Question

I am currently getting an object from my fauna database collection with an Index like so:

Get(
    Match(
        Index("byURL"),
        "rv49z1"
    )
)

I would also like to be able to increment a number variable (clicks) in the document I fetch each time I fetch it, ideally in one command.

Any help is greatly appreciated. Thank you.

Something like this should do the trick:

Let(
  { o: Get(...) },
  Update(
    Select("ref", Var("o")),
    {
       data: {
         clicks: Add(1, Select(["data", "clicks"], Var("o")))
       }
    }
  )
)
