Explanation:

The present perfect tense is when an action occurred in an indefinite time in the past or started in the past and is still relevant in the present. In other words, we can say that the present perfect tense talks about a past event that has present consequences. The simplest way of detecting it is the structure or form of "has/have + Past participle".
