Help Code Wix

Hello, how’s it going? Good morning.
I am making a web page, in which I have added some payment plans for my clients of a service that is offered to them, in these plans they go from 1 month, 3 months, etc. Said plan, I want my clients to hire a 3 month plan (for example) in their profile or in the status bar, to show the date in which I request and in which their plan ends. or, just show when your plan date ends plus the type of plan you contract.

How can I do this in code Wix? mentioning that I have the “Plans and payments” page and I am registered with Paypal.
