DeepL Plugin not available for Trial-Version?

I am currently intending moving avay from cafetran. For evaluation, I installed the trial-version of SDL studio 21.

I own a professional subscription of DeepL that I intend to integrate for testing. However, it seems that the required plugin cannot be downloaded with the trial license.

Since DeepL is quite deeply rooted in my processes, DeepL integration is an essential issue of my evaluation.

Is there a way to receive the plugin or to have alternative means for testing DeepL-integration?
