Pause Plugin

Hi Team,
We have WooCommerce Email Template Customizer Premium installed. Once we install the plugin, woocommerce start using the email templates provided by the plugin.

We need to customize all the templates, therefore need to pause these templates and activate them one by one when we finish editing.

We tried drafting the posts but the plugin disappeared, so we have to delete and re-install the plugin.

Please share what’s the best way to activate the template one by one?
