i want to submit two actions with one form and one submit button in laravel 8 - laravel-8

Question

In my app i want the user click on participate button to participate to an event and i want he will receive an email in the same time when he click !
The 2 function work well in the app but i can't make them in the same time when the user click on participate button !!
I have two routes with two different controllers:
Route::post('/participations/{id}','App\Http\Controllers\EventController#participate')->name('participate');
Route::post('/event/mails','App\Http\Controllers\EmailController#participate')->name('mails');
This is my form :
<form action="{{route('mails')}}" action="{{route('participate', [$event->id])}}" method="POST">#csrf
<div class="modal-body">
<div class="form-goup">
<label>Your name *</label>
<input type="text" name="friend_name" class="form-control" required="">
</div>
<div class="form-goup">
<label>Your email *</label>
<input type="email" name="friend_email" class="form-control" required="">
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-primary">Participate</button>
</div>
</form>
I can't find a way to fix that ! any help ?
Thanks in advance !
