Clocking on “Get Access Token” button does nothing

In the ‘Fulfill’ section (woocommerce-alidropship#/fulfill):
“This function will not work because access token is missing.”

When I click on the “Get Access Token” button
it redirects me to the ‘Update’ section (woocommerce-alidropship#/update)
where there’s another “Get Access Token” button. Nothing happens when I click on it.
