MAC not able to access Passport

I bought a Passport on April 1st. Store told me that could be used on either PC or MAC. WHile PC worked, MAC does not. I am unable. to change permissions to use the Passport

I tried to install PARAGON software as prompted, but error message
that it is incompatible with my version of Big Sur, 11.2.3on MAC and a newer version would cost $20

Any suggestions?
