Calculate Tax line by line option is not working on the Customer Invoice.

I see that the option to calculate the taxes on lines is set to Invisible.
https://github.com/fhe-odoo/avatax_connector/blob/eecce5a4e14e7c93a851491172bebbf1a35d73c4/avatax_connector/views/avalara_salestax_view.xml#L51
May I know the reason that why we are not allowing users to enable that?
We need this for one of our customer.

Even though, I customized the code and enabled the option.
It works good for Sales Order.
But in the customer Invoice, tax on lines are not calculated. But the global taxes are calculated.
I reviewed the code. I guess that the problem relies in wrong method name.
Please see https://github.com/fhe-odoo/avatax_connector/blob/10.0/avatax_connector/models/account_invoice.py#L175
The method name has to be compute_taxes I guess.
Forgive me I am wrong.
