How to add the ability to display information for a corporate client to your WooCommerce personal account?

Question

WooCommerce

How to make a separate tab in your WooCoomerce personal account, which will be displayed only for corporate clients?
In the tab, you need to implement:
- output for promotional offers,
- output of a file (individual price list) that a corporate client can download

Make a tab in your personal account, with the ability * for a corporate client * to download a file with an edited (price list).
As a result, I should see this file in the admin panel.

In short - how to display information from the admin panel individually for different clients?
And how to enable the client to upload a file in the WooCommerce personal account.
