Protobuf golang - How to read values from *_struct.Struct [closed]

Question

I am trying to convert Protobuf *_struct.Struct to map[string]interface{} what is the right way to do it?

func convertToMap(input *_struct.Struct) map[string]interface{} {
    ans := make(map[string]interface{})
    //code to fill the map based on input
    return ans
}

This is the Struct from protobuf repo: https://github.com/protocolbuffers/protobuf/blob/main/src/google/protobuf/struct.proto#L53

// The JSON representation for `Struct` is JSON object.
message Struct {
  // Unordered map of dynamically typed values.
  map<string, Value> fields = 1;
}

// `Value` represents a dynamically typed value which can be either
// null, a number, a string, a boolean, a recursive struct value, or a
// list of values. A producer of value is expected to set one of these
// variants. Absence of any variant indicates an error.
//
// The JSON representation for `Value` is JSON value.
message Value {
  // The kind of value.
  oneof kind {
    // Represents a null value.
    NullValue null_value = 1;
    // Represents a double value.
    double number_value = 2;
    // Represents a string value.
    string string_value = 3;
    // Represents a boolean value.
    bool bool_value = 4;
    // Represents a structured value.
    Struct struct_value = 5;
    // Represents a repeated `Value`.
    ListValue list_value = 6;
  }
}
