SerializedProperty it = tagManager.GetIterator();

while (it.NextVisible(true))

{

if(it.name == "tags")

{

for (int i = 0; i < it.arraySize; i++) 

{ 

SerializedProperty dataPoint = it.GetArrayElementAtIndex(i);

if(string.IsNullOrEmpty(dataPoint.stringValue)){

dataPoint.stringValue = tag;

tagManager.ApplyModifiedProperties();
