Utilize Polymer 3 component to import object values

In one of my polymer 3 components, I have declared an object property as follows:

 static get properties(): myInferface {
    return {
      myObject: {
        type: Object,
        notify: true,
        value:  {
          showMe: false,
          text: '',
          text2: ''
        }
      }
    };
  }

For rendering, I use the following template:

 static get template() {
    return html`
          <template is="dom-if" if={{myObject.showMe}}>
           <p>{{myObject.text}}</p>
           <p>{{myObject.text2}}</p>
          </template>
    `;

To define the component, I use the following code:

window.customElements.define('myComp', myClass);

Initially, nothing will be displayed as the default value of myObject.showMe is false.

When I import this component into another one and try to set the properties, it does not work:

<myComp> 
    myObject= {{
    showMe: true,
    text: "aaa",
    text2: "bbb"
              }}
</myComp>

I have also tried the following approach, but it still does not work. What could be the issue?
