I upgraded Postman to 6.2.5. It allows Teams for free user. Ok, so I created Team and started new collection within it.
On collection level I specified Authorization as OAuth 2.0, generated new Access token (using the button Get New Access Token) so it is now in Available Tokens. I don't know if the tokens are shared with other team members (I haven't invited them yet). But there is a hint
Heads up! These parameters hold sensitive data. To keep this data secure while working in a collaborative environment, we recommend using variables.
I know the variables but don't know how to employ them in this scenario. What is the correct way to setup OAuth 2.0 Authorization in collaborative environment? (I would like to keep it on Collection level so it could be inherited down the structure of folders and requests.)
