I'll share some information about connecting with the Guaranty Trust Bank (GTBank) account. Currently, the option to directly connect Guaranty Trust Bank (GTBank) through the bank feed is unavailable. However, you'll want to check with your bank if they've offered a CSV file. This way, you can manually upload bank transactions into QuickBooks.
Here's how to upload a CSV file:
Check out this guide for details: Manually upload transactions into QuickBooks Online.
I've also added this link here in case you need help with other banking tasks. Just look for responses that fit your concern.

Make sure your client is using QBO Global version for Nigeria
Consider having a virtual business account at Wise to manage their NGN balance. They may open a USD, a Euro and/or GBP account to deal with multi currency transactions and utilize the bank feeds if required.
You can only able to manage QBO UK version in your QBO Accountant UK account. To manage QBO Global version account, you may have 2 options:
1. You may open the account as the Primary Admin and they pay the monthly bill to your end. Another option, you may purchase an annual plan of it.
2. Ask them to open the account by themselves and invite you as the Accountant user. Your role will be the same as Company Admin.
