How to download excel template from storage before upload

I am developing a web application that imports from excel sheet and save into the database using maatwebsite-excel 3.1 and Laravel-5.8

public function collection(Collection $rows)
{           

    foreach($rows as $row)
    { 
        if(!$this->alreadyExist($row)){

            $enrollment = Enrollment::create([
                
                'surname' => $row['surname'],
                'other_names' => $row['other_names'],
                'dob' => $this->toPHPdate($row['dob']),
                'gender' => $row['gender'],
                'home_address' => $row['home_address'],
                'nationality' => $row['nationality'],
                'state' => $row['state_of_origin'],
                'lga' => $row['lga'],
                'town' => $row['town'],
                'village' => $row['village'],
                'admitted_into' => $this->isFilled($row['admitted_into']) && $row['admitted_into'] > 0 ? $row['admitted_into'] : null,
                'src' => 'import',
                ]);
                               


            if(isset($row['father_fullname']) && $this->isFilled($row['father_fullname']))
            {
                $father = Parentt::create([

Import Controller

public function studentForm(){
    return view('import.students');
}
public function importStudents(){
    Excel::import(new StudentsImport,request()->file('file'));
    return back()->with('success','Students records imported');
}

                    </form>
                </div>
            </div>

before users will import, I want them to be able to download the excel format for the import and go through it. The link will be available on the index.blade form for the import/upload.

The is the template path:

storage/companies/studentfile

How do I achieve this?

Thank you.
