Declined with proof

Thank you, but what if I didn't get the information on which episode in specific I will appear, since this is a film/Miniseries that hasn't aired yet?

And I see that the other actors aren't assigned to any episodes yet either

In this case the credit have to be added to the episode as mentioned in the Episode Guidelines, you can add the credits once you know which episodes you will be credited on.
