Giving permission to tax consultant to submit my data from mein Elster to tax office

[nssankar]

Hello All, My tax consultant asked me to give permission for him to submit the data from my Elster account to tax office and he said me to do this in my Elster account. But I have no idea how this works and where to find such permissions. Please someone help me with this. Thank you very much.
