What does it mean that the electronic version of the power of attorney for patent agency entrusted by the original agency has not been submitted?

From your description, your application was submitted by a patent agency for you, but you didn't have a power of attorney from the bookmark agent when you submitted it, so you lacked a power of attorney from the patent agent when you submitted it. What the examiner wants is this power of attorney. What you need to do now is to make a power of attorney. After your signature or seal, the patent agency will help you submit this active correction. You don't have the right to submit it on your own initiative now, unless you cancel the entrustment with that organization (it is not recommended to do that, it will only get more and more chaotic for you). The specific affairs agent will do it for you.
