I wont to create internal transfer entry account1 to account2 from python:

1. Access from backend  and call ('Internal Transfer' account.reconcile.model) in accounting Bank Reconciliation.

writeoff_btn =  self.env['account.reconcile.model'].search([
    *self.env['account.reconcile.model']._check_company_domain(self.company_id),
    ('rule_type', '=', 'writeoff_button'),
])

1. Access "validate" button and call from python.
2. Access "reset" button and call from python.
