Thank you for your answer. As I am new to Adobe Launch I am not very how to use DOM ready, I am trying to find documentation but it doesn't fullfil my needs. The tag I would like to add will just work updating the analytics code, however Adobe Launch is a bit tricky for me in this sense. Is there any recommendations?

Thank you Andrey. When I add this to the field you mentioned, I get some errors, should I update the code somehow before adding to this part?

Dear Andrey, thank you so much. There's a something mapped already to the development environment. Thank you so much!
