Security Not Showing

Hi!

I recently created a report with RLS created with the powerbi desktop and the tested it out and it worked perfectly with no error. For the next step I publish it to service and then go to the dataset and select the three dots for more options, but I am not able to see security so I can assign users to the role. Any help is appreciated.

I have the powerbi pro license and the datasets are from a smartsheet and an excel file.
