I got Stripe \ PermissionException error with new stripe api keys

Hello, Working with Stripe Connect in laravel 5.8 app and making :

\Stripe\Charge::create

I got error :

Stripe \ Exception \ PermissionException
The provided key 'sk_test_51*********************************************************************************************AE7z' does not have access to account 'acct_NNNN' (or that account does not exist). Application access may have been revoke

My code worked with different stripe account, but I need to set api keys of my client After logtin into stripe with credentials of my client I just activated the the Stripe connect, but looks like not all settings are set: https://prnt.sc/10vfict

1. Which steps have I to take next ?

2. I wrote to support under my client credentials, but my client not alwaysa available and as I have no acccess to his email account I ask if there is a way to read messages from support in stripe dashboard? I did not find such possibility...

Thanks!
