Make returned data extensible

I’m running into a situation where I need another plugin (ngx-datatable) to be able to modify the data being returned from the server. Right now it’s unable to do so because the data is not extensible.

ngOnInit(): void {
    this._apollo.watchQuery({
        query: getAllTheThings
    }).subscribe(({data, loading}) => {
        console.log(Object.isExtensible(data['theThings')); // false
    });
}

It would be super helpful if this was mutable out of the box. Failing that, does anyone have a suggestion as to how to maintain the observable state of the data but allow the other plugin to modify it?

Import * as _ from 'lodash';
...
Let copyOfData = _.cloneDeep(data);
