I've a perl script file (.pm) which has many functions like below

```
sub check_row {
    my ($class, %args) = @_;
.......
sub find_value {
    my ($class, %args) = @_;
.......

```

Is there any way I can call specific function either via C# or Powershell? I am not allowed to make any change in the .pm file. I am clueless as the tutorial I see on internet talks only about running perl module but not calling any specific function and passing and retrieving value.
