Open link in new tab or same page (not iframe) with router.navigate() doesn't work in Forge Custom UI App

I have a Forge App where I pass some HTML with a link to my Custom UI. By using a React.createRef() its possible to put that passed HTML with the link into the table where it gets displayed.

The passed link looks like this:
<a href="#" onClick="router.navigate('LINK_TO_CONFLUENCE_PAGE')">Link</a>

I use router.navigate() as it is described here (https://developer.atlassian.com/platform/forge/custom-ui-bridge/router/) with an import of router in the index.js of my static folder of the Custom UI, therefore I thought the passed link with the onClick-Tag should work there, but it doesn’t.

Did I miss something?

Thats a snipped of my code of the src/index.js that passes the HTML to the Custom UI:

import Resolver from '@forge/resolver';
import { requestConfluence } from '@forge/bridge';
import api, { route } from '@forge/api';

const resolver = new Resolver();
var returnValue = "";

resolver.define('getChildpages', async ({ context }) => {
    // REST CALL TO GET CHILDPAGES

    for(var i = 0; i < childpages.length; i++) {
		// REST CALL, WHERE selfLink GETS CREATED.
		
        returnValue += `<tr><td><a href="#" onClick="router.navigate('` + selfLink + `')">` + title + `</a></td></tr>`;
    }

    return { returnedTableContent: returnValue };
});

export const handler = resolver.getDefinitions();

And here is my code snipped of the Custom UI index.js in the static/app-name folder:

import React from 'react';
import ReactDOM from 'react-dom';
import '@atlaskit/css-reset';
import { invoke, router } from '@forge/bridge';

class App extends React.Component {
    constructor(props) {
        super(props);
        this.divRef = React.createRef();
    }

    componentDidMount() {
        invoke('getChildpages').then((returnedData) => {
            this.divRef.current.innerHTML = returnedData.returnedTableContent;
			// SOME INIT STUFF
        });
    }

    render() {
        return (
            <table id="searchableTable">
                <thead>
                    <tr>
                        <th>Title</th>
                    </tr>
                </thead>
                <tbody ref={this.divRef}>
                </tbody>
            </table>
        );
    }
}

ReactDOM.render(
    <App />,
    document.getElementById('root')
);

The necessary import { router } from '@forge/bridge'; is set there, but when clicking on the link nothing happens.

If someone is interested: Just pass the link as a data-attribute with the a-tag, read that out when clicking on an a-tag in the Custom UI index.js and pass that to router.navigate().
