I have a flow.
i have a app in azure with delegated permissions.
how do i get the correct access token with the http connector.
i have this:

i get this error:
{"error":"invalid_request","error_description":"AADSTS900144: The request body must contain the following parameter: 'grant_type'.\r\nTrace I
this is the http connector:

i have tried without json format in the body.
i have tried without the " around the variables.
every time i run the flow i always get the same error complaining on grant_type
all i have read is that grant type must be set to password and it is set to passoword.
but still i get the error.
