how do i add these features to my process diagram:

$-$ Check if login is successful. If not, after three failed attempts, generate a "Login failed message" and end

the process.

$-$ After the customer searches for an item, check the inventory database to make sure it is in stock. If not, a

stockout message should be shown to them and they should be looped back to the search function.

$-$ When a customer adds an item to the cart, then they should also be able to select a quantity.

$-$ If credit card verification fails, they should be given the option to retype the credit card information or use

another one up to three times. After three failures, the process is terminated.

$-$ Similarly, verify if the address is valid. If not, ask them to fix it$.$

Check for the correct flow of logic along all paths from start to end, and make sure you use the correct

connectors $($use only AND and XOR$).$ I am not looking for one correct answer. You can incorporate these

features in your own way $($by making reasonable assumptions$)$ as long as it makes sense.
