supportsInterface(bytes4) :
This function checks whether a given interfaceId is supported by the contract. It does this by comparing the given interfaceId to the interfaceId of the IERC1155CreatorExtensionApproveTransfer type. If the two match, the function returns true, otherwise it calls the super.supportsInterface() function to check if the interfaceId is supported by the parent contract. (autogenerated documentation)
setApproveTransfer(address,bool) :
This function enables or disables the approveTransfer extension for a given address (creator). It requires that the creator address implements the IERC1155CreatorCore interface, and then calls the setApproveTransferExtension function on the creator address to enable or disable the extension.
