UI Angular Developer who is skilled in Material design is needed

I have a UI page from Angular (which is ready) which needs to be modified and add some more codes to be done. I have a page which has a "mat-selection-list" and need to get the values when each one of them is selected and show as the label at the top using "matchips". In addition, I need to show the values when the button at the bottom is submitted. If you open the screenshot you will see the numbers on top of each section which needs to be shown. ** Please note that if the user remove the "matchips" from the top it should be impact in the list as well therefore, it should uncheck that particular checkbox in the list as well (They should be synced). **I will give you the source code when you sent the message.
