Chrome Extension Review Specialist Needed

I have a chrome extension that does the following action:
- pressing the key A it selects a predefined date in a calendar
- pressing the key Z it fills the quantity
- pressing the key E it clicks on next (the website changes page then)
- pressing the key R it clicks on the first available timeslot

I need to combine all the functions into the key A.
Also, if the first timeslot is not available anymore, it needs to click on the second available timeslot.

The website is only available for a specific IP, we will need to work through anydesk.
For now please.
