Inquiry Regarding Asset sell in the New FAB

Dear Team,
I would like to inquire about the process related to asset sell for newly created accounts in the new FAB:
How many days does it typically take for a newly created account to gain permission to sell assets?
Are there any restrictions regarding the ability of the Seller to sell assets?
Are there limitations on releasing multiple assets at once?
I would greatly appreciate any clarification on these matters.
Thank you for your assistance.
Best regards,
