Winner, I didn't quite understand the scheme. At the very least, I need to somehow make the already created map open, and in the editor. Because it's a pity...

codenameray, I tried in different ways:
1. Open the editor. Use "open" to open the file itself.
2. Open the editor, open any map. Then open the desired map.
3. Immediately click on the file with the desired map.
4. Open the editor and click on the file.
