PHP Stan error with return Union type in PHP v7, laravel

According to some conditions, I need to return int or Collection (the table data from mysql query or his count), Here is code what I did implemented.

public function myMethod(
Term $term,
int $id,
?bool $includeRecords = false,
?int $page = 1,
?int $count = 100
) {
$currentDefaultSegment = Segment:EFAULT_SEGMENTS[$id];
$filterFieldName = $currentDefaultSegment['type'] === 'opener' ? 'lastOpenDate' : 'lastClickDate';

$query = DB::connection(MYSQL_DB)
->table("my_table")
->where('status', 1)
->where('id', $term->getId())
->whereRaw("{$filterFieldName} > CURDATE() - INTERVAL {$currentDefaultSegment['duration']} DAY");

if ($includeRecords) {
return $query->limit($count)->offset(($page - 1) * $count)->get(); // It return Collection
}

return $query->count(); // It return int
}


But when I use this method, php-stan complain and seems like it does not recognize when would be Collection or Int. Error message: Cannot call method transform() on Illuminate\Support\Collection|int.

Here is code that is calling above method. $this->myMethod(prams here)->transform(....) // In this case myMethod return type should be Collection instead of Int.

Question: How to determine & force return type is only Collection or only Int according to the Use cases?

I've tried make 2 methods instead of One according to the conditions, but Almost method body is the same, so I dont think it is good idea to make 2 methods. But have no idea how to solve the problem.
