How to navigate to a Visualforce page when the Salesforce Flow is Finished?

We can use Lightning Out App and Visualforce page to navigate to a Visualforce page when the Salesforce Flow is Finished or Completed.

In the Visualforce page, window.open() JavaScript method can be used to navigate to the Visualforce page.

Sample Code:

Lightning Application:

<aura:application access="global" extends="ltng:outApp" >
    <aura:dependency resource="lightning:flow"/>
</aura:application>

Visualforce Page for List Button:

<apex:page standardController="Account" recordSetVar="accounts" sidebar="false" showHeader="false">
    <html>
        <head>
            <apex:includeLightning />
        </head>
        <body class="slds-scope">
            <div id="flowContainer"/>
            <script>
                console.log( 'Before JS Start' );
                let statusChange = function ( event ) {
                    if ( event.getParam( "status" ) === "FINISHED" ) {
                        
                        let outputVariables = event.getParam( "outputVariables" );
                        let strURL = '/apex/SampleVFPage?';
                        
                        for( key in outputVariables ) {
                            
                            strURL += outputVariables[ key ].name + '=' + outputVariables[ key ].value + '&';
                            
                        }
                        
                        window.open( strURL, '_self' );
                        
                    }
                };
                $Lightning.use( "c:FlowApp", function() {
                    $Lightning.createComponent(
                        "lightning:flow", {
                            "onstatuschange" : statusChange 
                        },
                        "flowContainer",
                        function ( component ) {
                            component.startFlow( "Sample_Screen_Flow" );
                        } );
                });
                console.log( 'After JS End' );
            </script>
        </body>
    </html>
</apex:page>

Visualforce page to Open from the Flow when finished:

<apex:page>
    {!$CurrentPage.parameters.exampleVariable}<br/><br/>
    {!$CurrentPage.parameters.sampleVariable}<br/><br/>
    {!$CurrentPage.parameters.testVariable}<br/><br/>
    <apex:form id="frm">
        <apex:commandButton
                            value="Back to Accounts" 
                            onclick="window.open( '/lightning/o/Account/list', '_self' );"
                            reRender="frm">
        </apex:commandButton>
    </apex:form>
</apex:page>
