Need Data-Handle for Combined CSS File Generated by SG Optimizer

Good Day,

We’d like to preload the combined CSS file generated by SiteGround Optimizer using an external method.

In order to accomplish the above and to account for all of the combined CSS files generated by your plugin, we need to know what is the data-handle (i.e., style-handle) assigned to your file.

The typical file in question is:

/wp-content/uploads/siteground-optimizer-assets/siteground-optimizer-combined-css-(unique number).css

Unfortunately, the method described at the top of your support section did not reveal a data-handle (i.e., style-handle) for the typical file in question.

Help appreciated. Thank you!
