Is it possible to access un-exported data

Summary
I've compiled following code using tinygo
//go:wasmimport env call
func _call(ptr uint32)
//go:noinline
func call(f func()) {
ptr := unsafe.Pointer(&f)
_call(uint32(uintptr(ptr)))
}
and the resulted wasm will call my host function with value a pointer to a memory with two u32: 0 (receiver), 1 (index of function in the table), and the table is as following.
And the generated wasm does not export this table, is there any way I can access this function $main.main$1
Additional details
I've got it working with wazero
, they exposed a function to retrieve unexported function defined in tables.
I am wondering if it's archievable in wasmer
.
