AGI tokens on my Ledger Nano X (ETH) what am I supposed to do with them to get AGIX?

Hi, Can anybody help me? My AGI tokens have been sitting on my Ledger Nano X (ETH) since I bought them. They were included in the snapshot late last month. However, they are still showing as AGI, what do I need to do to change them to AGIX? Totally confused…cheers…
