Attack simulation training - customize text hover of phishing link

Hello everyone,

I'm currently working in a phishing simulation and I wanted to know if it's possible to change the hover text of phishing link.

I tried directly in the html code as I'm doing my own mail template but it doesn't work, seems like the tool is overiding my code :

I'm sure this works, I tried just by open it in my browser

Do you have an idea ?

Thanks and have a nice day !
