Issue with searching customers in admin

[xcom-magento]

Hello,

Our customer noticed an issue in the admin while searching customers.
For some customers there is the following error:

main.CRITICAL: TypeError: Commerce365\Customer\Model\Command\GetCustomerEmailById::execute(): Return value must be of type string, bool returned in /vendor/commerce365/module-customer/Model/Command/GetCustomerEmailById.php:24

We have fixed this by adding bool as accepted return type when no result is found. We think this is okay because in the parent method call (vendor/commerce365/module-customer/Ui/Component/Listing/Column/ParentCustomer.php::42) there is also a check when there is no email found.

Could you check this and update the module?
Thanks in advance!
