Hi @RicardoE105, I am trying to add a new field into the get token request's body something like

const options = {};
if (credentials.authentication === 'body') {
Object.assign(options, {
	headers: {
		Authorization: '',
	},
	body: {
		client_id: credentials.clientId as string,
		client_secret: credentials.clientSecret as string,
	},
});
}

if(credentials.authExtraBody) {
    // { appId: 'string' }
    Object.assign(options, credentials.authExtraBody)
}


return oAuth2Client.credentials.getToken(options);
	

The auth provider required to add the app id as exra field of the get token request.

Do you have any idea the best approach for that?

thank you so much!
