execute some codes in heap memory?? (ARM,ARM64)

Can I execute some code(asm -> hex) in the heap memory?
The x86 architecture was successful, but armv8 failed. (tested on Android os)
Is it because the code is not designed to run in the heap area in the ARM cpu?

thanks for reading
test code
usinged char prefix[] = { 0xE0,0x01,0x80,0x42,0xc0,0x03,0x5F,0xD6}; // ARMv8
char *func = (char *)mmap(0, 8, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANON, -1,0);
memcpy (func, prefix, sizeof(prefix));
int result = ((int (*)(void))test_function)();
return result;

x86 prefix
push ebp
mov ebp, esp
mov eax, 15
pop ebp
ret 0
=> unsigend char prefix[] = { 0x55, 0x89, 0xE5, 0xB8, 0x0F, 0x00, 0x00, 0x00, 0x5D, 0xC2, 0x00, 0x00 };
