In Fabric 2.4, channels are created using Fabric-SDK-Go in a non-system channel way

[shengwenbin]

Hello, I'm using fabric-sdk-go for creating channels. I created channels using the system channel method and created channels via the SaveChannel function in go-sdk. But when I upgraded to fabric 2.4, when I used the non-system channel mode, no .tx file was generated, only a .block file, and there was no function in the go-sdk to create channels through the .block file. Do you have any suggestions for this problem?
