Basic Question :How to get token correctly after complete registration

[Pongthorn Sangkaphet]

I installed Django-oauth-toolkit and followed the 2 links below to register the app.
after I registered the app completely, I didn't know which was the next step I needed to perform to obtain the token.

• Part 1 - Make a Provider in a Minute

• Getting started: Client Credential

These are steps that I did already

1. register the app as figure below

2. get a token this way (I am not sure whether this is the way of generating Token )

My purpose is to obtain a token to use on Google Vertext-AI Search in order to enable my Google search module to connect to my web application as the link and figure below.

I place the search widget into a web page in a web application, but at present, I can not make it because of the token problem as I ask you.

Add a widget with an authorization token

Thank you
