Custom GPT Bug - Hyperlinks not clickable

It looks like hyperlinks produced by custom GPTs are not working. Here is my GPT which provides links to research papers: https://chat.openai.com/g/g-bo0FiWLY7-researchgpt. However, I noticed that the Bing functionality with ChatGPT can still provide clickable links via its native citation format ["]. Do I need to move to this format? Anyone know how to correctly do this?

…since you cannot track activity out chatgpt using parameters (such as UTM values)…how are builders currently tracking clicks and users leaving their GPT’s?
