Mailto not recognised

I have an elementary html
It’s purpose is to send emails
It is written in javascript
On my site the html mailto: works – it opens the installed mail client
The app I created with volt builder works everything but will not recognise mailto:
The android app was created as a debug

What do you advise?

You’ll need to add mailto to your Allow List in the config.xml: Allow List Guide - Apache Cordova

<allow-intent href="mailto:*" />
