To start connecting your own numbers, you need to have a verified company in Facebook Business Manager.
Check the current status of your company on the pages:
https://business.facebook.com/settings/info
https://business.facebook.com/settings/security
If your company has not yet been verified, open the page https://business.facebook.com/settings/security and check if the "Start Verification" button is active.
Perhaps our instructions on how to activate a button in the Facebook Business Manager will be useful to you in order to start the procedure for verifying a company:

Go to the page https://business.facebook.com/settings/security, the "Start Verification" button should now be active, click on it and follow all the steps to verify your company.
After your company is verified in Facebook Business Manager, you can start connecting any of your phone numbers to the WhatsApp Business API following our instructions: https://aiapps.pro/tpost/59pdtfky81-how-to-access-and-connect-your-own-phone.
