It means that you cannot qualify under that bullet point to enter Croatia. But you can get a digital COVID certificate on the basis of a negative test. Such certificates are valid for 48 or 72 hours, depending on the circumstances. See https://gruenerpass.gv.at/getestet/:
Ich bin getestet.
Wie lange gilt mein Zertifikat in Γsterreich?
Ein PCR-Test gilt 72 Stunden.
Ein Antigen-Test, der in einer TeststraΓe oder Apotheke gemacht wird, gilt 48 Stunden.
Translation (from the website; it's not precisely the same in English as in German):

How long is my certificate valid for?
A PCR test is valid for 72 hours.
An antigen test which is made at a testing site or at a pharmacy is valid for 48 hours.
