Welcome! Thank you for your question.
Unfortunately you cannot. I get a power of attorney the person must be competent to understand, agree and sign the document granting someone the authority to speak on their behalf. If the person is unable to speak on their behalf you have to request the court deem them incompetent and appoint a guardian for this person.
Here is the NY website with forms.
Thank you for the info. My younger sister and I are her only family. Will the guardianship allow us to gain beneficiary info from her bank?
