FrappeCRM x Zoho Email

Hello! I found a problem that doesn’t let me set Zoho Email with Frappe CRM.

Trying to “Connect to Zoho” returns Invalid Client, which if we read their docs, means that response_type isn’t TOKEN. Frappe tries to use response_type CODE.

Returned link from testing “Connect to Zoho”:

I need to force it to use TOKEN, but how?

It works, just sends emails very delayed, like 10-30mins delay.
