Item-Purchase-Code instead of Token used for updates

Dear team, I have the following problem:
On May 7, 2024, my colleague bought your theme.
He created a token for the updates. Unfortunately, he mistakenly did not enter it in the field for updates. Instead, he entered the item purchase code.
To make matters worse, he did not write down the token anywhere.
So updates obviously did not work, which is why I had to generate a new token for OAuth client ID: paulsen-automaten-vbyhzpzo.
Unfortunately, the system tells me that it is not working:
…………………………
The following errors occurred:
Purchases: Received error code 403 from Envato: Forbidden:
– reason: invalid-token
username Received error code 403 from Envato: Forbidden:
– reason: invalid-token
email Received error code 403 from Envato: Forbidden:
– reason: invalid-token
Purchases: Your purchases cannot be accessed. It cannot be checked whether there are any updates.
………………………
What can I do to reconstruct the correct token?

Kind regards,
Conny
