automate a process in a web browser

I introduce myself I am Eduardo, I currently have a small netflix business in which I need for the moment to automate a process that takes us a lot of time in human work, I describe the process below. I get from a database in excel, access or even google sheets, the username (email) and password of an existing user on Netflix, then I have to log in, it is worth mentioning that to log in I require a proxy server that is fixed, since it gives me the same IP until I rotate it manually or I can even configure it through a rotating link or configure it to rotate IP from time to time, Well, once I log in correctly, I check if it is possible to ADD AN EXTRA MEMBER to the current account, this is done directly on the page ([login to view URL]) and this is true when 1: The plan is STANDARD OR PREMIUM 2: You have enabled the "Buy an extra member slot" since in some cases due to the payment method, it is not possible even the plan is the correct one. Now, if there is already an extra member within the account, then delete it and add ours. To add it, the following is taken into consideration, the name of the first profile of the netflix account is placed in the name field and in the email to invite it is the same name of the email, for example if the email of the account is hola @ [login to view URL] then the email to be invited will be hola @ [login to view URL] which is our domain. I would like the option to modify the domain to be placed through a text field, this is because I have several domains and I need extra members in these different domains. Once the invitation has been sent and STILL inside the main account, you have to go to "[login to view URL]" to extract the invitation link from this field "Copy invitation link Get an invite link to paste in an email, text message, etc. Copy link" and once the link has been copied, go to that link in the browser example link: "[login to view URL]" Once that page loads and still using the proxy, a 6-digit password will be generated randomly, it can include numbers and letters, if not it is possible to generate it, then there is a text field where I indicate what password will be written. Finally save the email and password. There is flexibility for the program/script/bot to be graphical (perhaps in javascript) or automated with selenium and python, where users and passwords can be received through a .txt file in the format email: password, the implementation of the proxy is of utmost importance. Any questions please ask me. Thank you very much for your attention.
