Configure the following fields from the modal that opens:
Variable field
Key: This is the key or name you specify for the session variable. The key identifies the variable and you can access the data using this name within the system. For example, “user_id” for a user name or “username” for a language preference.
Value: The value you set when defining the Session Variable. For example, the value of the “user_id” key could be the unique ID number of a user, or the value of the “username” key could be a name such as “user1”.
Read Only: Determines whether the Session Variable is read only or not. If “Read Only” is checked, the session variable is read only and its value cannot be changed. If unchecked, the value of the variable can be changed during the session.
Then you can add the variable by clicking on the “ADD” button on the right side and save it with the “SAVE” button.
