A free GitHub decompiler almost certainly will not restore a modern EA to working, editable source code.
Tools like Ghidra, IDA Pro, or custom Python scripts can read the raw bytes of an .ex4 file.
Searching on Stack Overflow often reveals that finding a "proper old" decompiler is challenging 1.2.4 . Significant Risks of Using Free Decompilers Ex4 To Mq4 Decompiler Github
