Present Perfect Continuous

 Present Perfect Continuous 

We use this tense in the below statement.

When describing an action that started in the past and is currently continuing or has only recently come to an end, the present perfect continuous tense—also referred to as the present perfect progressive tense—is employed. The construction involves employing the present perfect auxiliary verb "have" in conjunction with "been," as well as the present participle form of the primary verb (verb + ing).
