Go Back into WebViewer

I wanted to create a simple app that uses the webviewer component to display the website of our parent association, the problem that once I enter the web pages I can not go back, how can I solve it?

for now the only solution found was to open the web site not with webviewer but with openlink using the external browser, it is functional but it leaves me puzzled, I hope to have some advice from who is more experienced than me
