It's not a day action, so no GM confirmation. There's a clause that you can't talk about Death Note until Shinigami does and since it was revealed. Users can check with GM if this is true or not since you were the first who broke that clause and now that you mention it I'm not sure it does count like that.
Anyway the previous user passed the Notebook to you since they thought you might wanna be immune to the contract and if you are not mod killed they were right.
