Perfect progressive/continuous tense have:
have/has/had + been + present participle
Present perfect continuous:
I have been waiting for two hours. She has been waiting for two hours.
Past perfect continuous:
We had been waiting for two hours. She had been waiting for two hours.
A sentence in the perfect progressive tense includes a form of "have" + "been" + the present participle "-ing" form of the verb (e.g., "I have been studying"). The usage indicates that an action started in the past, continued, and is still in progress at the time of speaking.
