Salesforce classic had dedicated URL to "Choose Priceook" but not in  Lightning. We have custom VF page to add products and wondering what is best way to route users to select pricebook if one does not exist in Lightning.

Flow
- Click custom "Add Products" button
- Check if Pricebook is attached to opportunity
- Redirect to "Choose Pricebook"
- User selects the pricebook and then redirect back to custom VF page

Above flow is working in classic and need to make it workin in Lighrning.
