Only allow users to type integers for phone number input field and makes it so it bring up the numeric keyboard

Make it so when the user is typing in the phone number input field they can only type integers. Also make it so when clicking into the input field it brings up the numeric keyboard

Here's how we do the keyboard part: this.phoneInputDOM.setAttribute('inputmode', 'numeric');

Reach out to Mel if you want to know how Studio devs are only allowing users to write integers. It actually can get pretty complicated since different devices have different keyboards and you need to consider autofill and copy/pasting.
