Override bulk.js and bulk.phtml vendor files on my app/code

Do you see anything obviously wrong here?

I am trying to override

1. vendor/magento/module-configurable-product/view/adminhtml/templates/catalog/product/edit/attribute/steps/bulk.phtml

2. vendor/magento/module-configurable-product/view/adminhtml/web/js/variations/steps/bulk.js

I tried adding there files to my local

1. app/design/adminhtml/TTT/FFF/Magento_ConfigurableProduct/view/adminhtml/web/js/variations/steps/bulk.js

2. app/design/adminhtml/TTT/FFF/Magento_ConfigurableProduct/view/adminhtml/templates/catalog/product/edit/attribute/steps/bulk.phtml

Then this

1. app/design/adminhtml/TTT/FFF/Magento_ConfigurableProduct/templates/catalog/product/edit/attribute/steps/bulk.phtml

2. app/design/adminhtml/TTT/FFF/Magento_ConfigurableProduct/web/js/variations/steps/bulk.js

None of these changes worked.

Can anyone told me the exact path I should be using or point me at what’s wrong on those I tried? Thanks!
