Using funclatency.py to trace bpf_map_lookup_elem

Greetings, I have been experimenting with the `funclatency.py` tool and trying to trace the eBPF helper function `bpf_map_lookup_elem`. To do this, I run the following command: `sudo python3 funclatency.py bpf_map_lookup_elem`.

The tool reports: `Tracing 1 functions for "bpf_map_lookup_elem"... Hit Ctrl-C to end`. While it's tracing I run the syscount BCC tool using `sudo python3 syscount.py -L`, that from my understanding of the code frequently uses this helper to store latency measurements. However, `funclatency.py` does not print anything during or after its execution.

Is there any reason that `funclatency.py` should not be able to trace eBPF helpers? When I run the tool to trace other kernel functions such as `do_sys_openat2` or trace libraries such as `c:read` it prints the latency distribution as expected.
