I'm unable to extend the FieldRadio widget and seeing 'missing widget:....'.  The widget has been registered so why do I continue to see this ?

I can see that radio_reduce_selection has been registered from the output of the console.log statements.

Thank you .......

form_widget.js

odoo.define('customs.radio_reduce_selection', function(require) {
    "use strict";

    var registry = require('web.field_registry');
    console.log(registry);
    var relational_fields = require('web.relational_fields');
    console.log (relational_fields);

    var ReducedRadio = relational_fields.FieldRadio.extend({
        init: function() {
            console.log('Hi Bye ZZ');
            this._super.apply(this, arguments);
            let decrement = 0;
            let value_copies = this.values? [...this.values]: [];

            for (let index = 0; index                 if (value_copies[index].includes('export_contact')) {
                    this.values.splice(index - decrement, 1);
                    decrement++;
                }
            }
        },
    });

    registry.add('radio_reduce_selection', ReducedRadio);

//    return ReducedSelection;
});
