How to allow Managed AppleIds to download apps on their own?

Hi breitseite,

We appreciate you reaching out to us.

We’d like to gather additional details that may help us be in a better position to assist you.

Are you a Managed Apple ID user?

If yes, please contact your administrator.

As mentioned in the article below, "Because Managed Apple IDs can't make purchases, administrators may assign content to your Managed Apple ID or assigned devices."

"The company that issues your Managed Apple ID owns your account. Your IT administrators can access your account at any time and make the following changes:

• Restrict access to your account
• Remove your account
• Update your account information"

You can use the article below as a reference.
