From what I gathered when booking a few weeks ago, you don't need to create a Pocket Concierge account but you
do need to enter your primary Plat Charge card at the time of booking. Pocket Concierge will bill your card immediately to confirm the reservation.

I opted to create an account anyway so I could retrieve the booking and easily cancel/modify if needed.
The $200 statement credit hasn't come through yet, but that may be because it's possible to cancel Pocket Concierge bookings - so I'll wait until after my reservation (late October) to reach out to Amex. The T&C are quite ridiculous unfortunately - "the credit should appear on your billing statement within 5 business days from qualifying spend but
may take up to 150 days from the offer end date". The dining credit in Amex Offers also seems to span multiple years, so I don't think we can expect that to trigger or move to the Savings tab like a normal Amex Offer would.
I'm definitely pushing my luck here but I also found Amex Japan is running a Shop Small
20% cashback campaign (up to 2500 yen) which includes spend at Pocket Concierge. The T&C mention that only Japan-issued Amex cards are eligible.. but it let me register, so lets see what happens

Somewhat off topic, but from the wording of your question I guess you may be referring to the yellow bar on the PC site that reads
Notification when registering for a credit card?
Compared with how this is written on the Japanese site, the English version could be better translated as "Notice about the entry of credit card details" or something along those lines. The actual notice is that they will pre-auth your card a small amount to confirm it's valid when adding it to a Pocket Concierge account. The slight mistranslation is because the same Japanese word can mean either "register/registration" or "entry" in English, depending on the context.
