login/signup with SPC

Hello, I have a problem
I use wprocket only to optimize files
And I use super page cache for cloudflare cache as well as fallback cache
To register and log in, I use the Digits plugin modal , which I have placed the modal button in the header menu
When the user clicks on login, the modal opens and performs the login actions and enters the site, after that the button does not change anything and still by clicking on the button, the login modal opens and does not enter the user panel!
This problem is directly related to the cache
How can I remove this item from the cache so that when the user enters, as designed in the theme of my site, the button’s name will change to the user’s name and go to the user panel page with a click?
