https://github.com/laravel/framework/blob/9.x/src/Illuminate/Database/Eloquent/Concerns/QueriesRelationships.php

    public function whereRelation($relation, $column, $operator = null, $value = null)
    {
        return $this->whereHas($relation, function ($query) use ($column, $operator, $value) {
            if ($column instanceof Closure) {
                $column($query);
            } else {
                $query->where($column, $operator, $value);
            }
        });
    }

here is my solution

    public  function whereRelation($relation, $column, $operator = null, $value = null)
    {

        if (is_array($value)){
            return $this->whereHas($relation, function ($query) use ($column, $operator, $value) {
                if ($column instanceof Closure) {
                    $column($query);
                } else {
                    $query->whereIn($column, $value);
                }
            });
        }
        return $this->whereHas($relation, function ($query) use ($column, $operator, $value) {
            if ($column instanceof \Closure) {
                $column($query);
            } else {
                $query->where($column, $operator, $value);
            }
        });
    }
