POE Guild Stash Tabs transfer to POE2

Hi Support

My brother and I have been trying to figure out how to get our POE1 Guild Tab's transfered to POE2 Guild Tabs.

I seeem to be leader in POE 1 and he is on POE2 but we have tried promoting each other and restarting game and the tabs never show up.
Also not sure if my personal TABs came accross as well



Thank you in advance
