To submit your brand to compliance you need to first upload your brand within the "Profile & Branding" tab of your Account Settings.
After you fill in all the fields click save and it will automatically send your submit request to your compliance team.
To verify if the submission has been sent, you'll see a yellow message at the top of your profile appear “Brand Awaiting Approval” as shown in the image below. Once approved the message on the top will disappear and your brand will be created/updated. A notification will be sent to you via e-mail once compliance has reviewed your brand.
