Action to update data in table after approval

[digisenz_g2020]

I am trying to create an action which needs to triggered when user clicks on approve button and specific set of data from the row to be copied to another table.

Table A:
Invoice, Date, Name, ID, Fees, Fees Validated

Table B: (Once approved, Fees Validated = True)
Like to perform an action which inserts data to Table B
