How to detect SMS messages in "Ionic Capacitor" without using the code "getAppHash()" of the sms retriever

I am working with "Ionic capacitor", I need to receive the SMS message coming from a server with a validation code. I only found the "sms-retriever" plugin but it only works by sending the code that generates this.smsRetriever.getAppHas(); Does anyone know another way to detect the arrival of SMS messages?
