How to use c/aquery to find the dependents of an anon_target

Given a situation where I have multiple named non-anon targets depending on the same anon_target, is there a way I can find what all those non-anon targets are? I think what I'm looking for are the rdeps of some covering target universe over those named targets on that anon_target. But whenever I try to use an anon target in a query, like something like this:

```
buck2 cquery "rdeps(//program:lint, anon//:lint_report_single@15ca92b70428afb8)"
```

buck2 says:

```
Error evaluating expression:
rdeps(//program:lin<>nt_report_single@15ca92b70428afb8)
