Stripe Checkout 2.0: Edit processing text

Hi everyone,

Does someone know, how I can edit (translate) the processing text of the stripe checkout? I have selected Redirect (Checkout 2.0) as Checkout Type:

If someone want to donate some money, they have to enter their name and mailing address, before the stripe checkout will open. There is a short manual, how they will be redirected to the stripe checkout. But this manual is in English and my website is in German at the moment.

In the “Stripe Gateway Documentation” it’s written, that it should be possible to edit the processing text. But I couldn’t find, where this should be possible.

Thanks in advance for your reply!
