[Grammar] In my current job, I am / have been delegated

[uktous]

Hi,

Background:
My boss would give me more and more duties every week.


Question:
Should I use "am or have been"?

Sentence:
In my current job, I am / have been delegated more and more reponsibilities.

Thanks

In my current job, I am delegated with more and more responsibilities on a weekly basis.
