(2) Create a Slack App

Go to https://api.slack.com/apps and go straight to Create New App. Choose your Workspace and press Create App. Then, click on your app and go to Add features and functionality -> Permissions -> Scopes and add the following scopes in User Token Scopes (be careful, User Token Scopes NOT Bot Token Scopes):

• channels:history
• channels:read

Then install the app in your workspace (you can go to OAuth & Permissions section and press Reinstall app), accept the permissions and copy the OAuth Access Token.
