No information about the next step once a vendor is added (multivendor admin app)

Is your feature request related to a problem? Please describe.
Once a vendor is added, there is a confirmation saying "Vendor added". But there is no information about the next step to follow.

Describe the solution you'd like
The confirmation message should also include the next step to follow (for ex Scroll below to the Vendors section below, use Search interface to find your email id and click on Restaurant microcopy to create your profile)

Describe alternatives you've considered
Once the vendor is added, bring him directly to the "Add Restaurant" page

Activity

Start at the vendor-add confirmation flow in the multivendor admin app and trace what happens after a vendor is successfully added. Done means the confirmation explains the next step, or the user is navigated directly to the Add Restaurant page, with the chosen behavior working in the admin flow.
