What is the proper location to store helper methods in Cucumber-Java?

I have two methods:

public void openEditUserModal() {
   adminUsersPage.admin_user_table_first_user.click();
}

and

public void waitForUserModal() {
   this.wait.until(ExpectedConditions.visibilityOf(adminUsersPage.admin_user_modal));
}

I initially had these methods as standalone clicks and waits in my step definitions but figured that since they will be reused a lot, it would be good to make helper functions for them.

Is it bad practice to have helper functions in my step definitions file?

Would it be better if I put them in the Page Object file?
