    It is advised to extract the actual search for the function call into a separate method since it can be re-used later.
    The `findElementForParameterInfo()` implementation should find all matching function definitions and store them using `setItemsToShow()` of the context parameter.

    Implementations return `null` if an appropriate element could not be found or if it is different from `getParameterOwner()` of the provided `UpdateParameterInfoContext`.
    If `null` is returned, the `dispose()` method is called.
 3. The `processFoundElementForUpdatingParameterInfo()` method is called which allows for additional adjustments of the `UpdateParameterInfoContext`.
    By default, this method does nothing and it's usually not necessary to implement it.

 It is recommended to adapt tests for [dumb mode](indexing_and_psi_stubs.md#dumb-mode) since the results might be surprising,
 and more changes to the handler might be required for better results.
