Minecraft command blocks locate?

- in Servers

So. I'm going to start over. I play with friends on my Minecraft Java Edition server. It is a Nitrado public server in 1.15.2. A buddy deactivated TNT a long time ago using a kill command block. He hid it and made it active forever. He doesn't want us to blow up, and I'm the owner of the server. He has now distributed many of these blocks on the map and collected a ban. Now I want to locate the command blocks with the Nitrado app. How does it work? Is there any other way to deactivate the command, but that other command blocks are still working? Loren with TNT are also deactivated.

Can someone help me?

Are creeper disabled?

No, creepers are active. But I want to find the command blocks with the app so that I can use TNT.
