Stake pool registration does not show in ledget

Hello folks,

I am following the Stake Pool Course. I just finished the Stake Pool registration. But I don’t see my stake pool id in the ledger. I submitted my transaction without error. What did i miss? here is my pool id = pool153zkfr5wxkencazev3nxx33xe2ynefljl07n25wruzrpsxveana. I am in testnet.
