iCloud data recovery concern after new Apple ID setup on iPhone 18 Pro

I lost my IPhone 15 and then bought an IPhone 18 Pro. I started ICloud recovery but had to open a new temporary Apple account meanwhile as I needed access to certain banks etc. A new icloud has been set up on the new account. I am worried in case I cannot recover my old icloud data. I cannot now find any info regarding my start of recovery from the old phone. How can I ensure the recovery process is still going ahead and that I can add the data to my new IPhone 18?
