Looking for a way to create a condition for when a user has visited a link on a WordPress site, a checkbox gets checked. I am currently using Gamipress to manage the data, currently, the user needs to check the box of themselves in order to change the state however I'm needing to add an additional condition where when the user has clicked something specific the checkbox gets a checkmark added.

I'm new to Javascript but would like to implement it with JS if possible to have the most control. For context, it is for a to-do list for a user to complete tasks off of. This would be so when a user visits a resource, the checkmark gets added. If anyone has any pieces of advice on how to make this happen it would be greatly appreciated!
