All template files are available in templates folder inside plugin files. Templates files contain the markup and template structure for frontend popup modal.
When you open these files, you will notice filter and action hooks that will allow you to add/edit content.
You also can overwrite templates files like the WooCommerce templating from your theme. Create a directory as /wpr/templates/ and copy template file inside the directory.
Example: To override template-modal.php file by your theme then the file structure should be wp-content/themes/yourtheme/wpr/templates/template-modal.php
Note: You need some development knowledge to overwrite template files or it may cause an error.
