Missing new-session page in v3

This page doesn't seem to be present in v3:
https://supertokens.com/docs/session/common-customizations/sessions/new-session#how-to-create-a-new-session

https://github.com/supertokens/docs/blob/master/v2/session/common-customizations/sessions/new-session.mdx

We need a similar page, explaining how a user can create a new session in different frameworks.
