UREGENT!!! Sender name in self addressed pre-paid envelope for Passport return

[Thinkin]

I got the request to mail our passports in a pre-paid self- addressed envelop so that they can send us the Permanent Residence Visa along with the CoPR document. My question is in the self-addressed envelop what is the sender name and address I should put? Should I put sender or From Address (for return) as:
CPCO – PR VISA
US Permanent /Temporary Residence VISA/Passports
365 Laurier Av.
West Ottawa ON
K1A 1L1

Also the Fedex shipping label form asks for a Phone Number for the sender and in the IRCC instructions it was mentioned not to put IRCC phone number. Do you know what number to put here for Fedex?

I am closing on the 30 day deadline to send the passports.

Please see instructions CIC sent to me regarding self-addressed envelop and shipping the passport below.

Pasting the relevant details from STEP 3: PREPARE THE REQUIRED DOCUMENTS section of the letter CIC sent:
One pre-paid return envelope for the return of your passport(s) and Confirmation of Permanent Residence documents: DO NOT SELECT “Schedule a pickup”; DO NOT put IRCC Phone Number or email address. If your documents are being returned to a mailing address in the U.S.A, please submit a self-addressed shipping label along with its commercial invoice and a returning envelope from FedEx, UPS or Purolator.

Pasting the relevant details from STEP 4: SUBMIT THE REQUIRED DOCUMENTS section of the letter CIC sent:
If you have a mailing address in the U.S.A., please submit by courier in a single package all required documents {including Passport(s) OR photocopy(ies) of passport(s)}, to the following address:
