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 from the multivendor admin app flow that displays the “Vendor added” confirmation and inspect how the vendor-add completion is handled. Decide between showing the described next-step guidance and navigating directly to “Add Restaurant”; the work is done when the post-add flow clearly guides the vendor to create a profile or reaches that page, with the existing confirmation preserved.
