Permission issues in WhatsApp Business Platform API

Question

I have a Meta App for using WhatsApp Business Platform. So I follower every instruction on the official docs (https://developers.facebook.com/docs/whatsapp/business-management-api/get-started#1--acquire-an-access-token-using-a-system-user-or-facebook-login):

• Added a system user
• Gave administrator permissions
• Created the bearer token
• Assigned the app as an asset and gave total permission
• On WhatsApp account I added the system user and gave total permission.

Yet I get (#200) You do not have permission to access this field on every request! Or similar error messages. What else do I need to do?

EDIT: Im trying to send a message https://graph.facebook.com/v18.0/{my phone id}/messages and the exact message Im getting there is You do not have the necessary permissions required to send messages on behalf of this WhatsApp Business Account and error code 200.

I used the Access Token Debugger and these are my permissions business_management, whatsapp_business_management, whatsapp_business_messaging, public_profile so it should be fine.

Also, I checked that my user has a role in the app, and it's an administrator.
