Get parameter name in Clion plugin

In a Clion plugin, I need to get a parameter name at the caller side, e.g. if a function is declared:

```void fun(int abc);```

and called

```fun(42);```

then when invoking an intent on '42' PsiElement, I need to get the corresponding parameter name, 'abc' in this example.

In a similar plugin for Intellij I get the parameter name using PsiCallExpression.resolveMethod(), which contains the list of declared parameters. How can I achieve a similar result in a Clion plugin? It is clear it should be possible, since the IDE itself displays parameter name hints.
