Hi,

If you are using Odoo online, there is no option to add third party apps to the odoo online instance. Either you have to move to odoo sh or use odoo in on premise server, so that you can add third party apps.

For this case, actually we expect odoo to provide this. You can create support ticket at:  https://www.odoo.com/help  and see what Odoo is saying about this.

Thanks
