How to check user role and show select option in laravel

I have users with different roles, like Admin,Employee,Secretary,etc.

And i have a page for send letter, in this page i have a select option to show indicators.

I want when user with Secretary role open this page, see all of the indicators but other users with other roles just see one indicator like internal letters, how can i do this ?

I have a relation between role and user :

User Model

public function roles()
{
    return $this->belongsToMany(Role::class);
}

Role Model

public function users()
{
    return $this->belongsToMany(User::class);
}

This is select option in send letter page :

<select class="col-12 border mt-2 pt-2" name="indicator_id">
        @foreach($indicators as $indicator)
                <option value=""></option>
        @endforeach
</select>

As you can see, indicators comes from somewhere else.

This is Letter Controller to show send letter page :

$indicators = Indicator::all();
return view('Letter.add', compact('indicators'));
