I created a simple LWC to be called from Actions and added to the "Salesforce Mobile and Lightning Experience Actions" section in the page layout.  The "Send Mail LWC" action displayed and worked properly when I logged in from a web browser, but not displaying in the Action list in Salesforce Mobile app.

Did I miss any configuration?

import { LightningElement, api } from 'lwc';
export default class DispatchIssue extends LightningElement {
