The _sync_google_calendar method was copied in https://github.com/odoo/odoo/commit/24c2d7e9d609f02b1814be0faf82352bfeb45d96 in the google.calendar.credentials model from res.users but it was not useful or used. This method makes more sense on res.users model. closes odoo/odoo#92835 X-original-commit: f78431507ec9a5e2d9f1d2847d723e1f7bfeca11 Signed-off-by: Yannick Tivisse (yti) <yti@odoo.com> Signed-off-by: Arnaud Joset <arj@odoo.com>
