Spreadsheet automatically adds contacts to linkedin

I need a macro / spreadsheet that gets a list with two columns: Linkedin URL and email address. The work can be performed as follows: 1. Each link should be opened in the browser: I imagine chrome as the only option. 1.1. If the person is your contact, nothing should be done and a message saying that the person was already a contact should be returned to a third column in the spreadsheet. 1.2. If the person has previously invited you, you accept the invite and inform the spreadsheet in a third column that you have accepted the connection request. 1.3. If the person is not already a contact and the possibility to send the invite directly appears, they should be sent and a message saying that the action was taken should return to the third column of the spreadsheet. 1.4. If the person is not yet a contact and the possibility to send the invite directly and is requested and email address appears, the parameter of the second column should be passed and the invite sent, stating that the invite was sent and the required email 1.5. If the invite cannot be sent directly, the spreadsheet will access the "plus" button next to send message and then send the connection request: This is usually the case for third-level contacts. Error messages must be returned to the worksheet. There should be a time lag between accessing two links. There should be a limit of open links at the same time in the browser (I suggest a maximum of 10) Each window / tab should be closed after the send / accept connection action is taken.
