Postman doesn't have permission to open file

im running ubuntu 20.04. installed postman snap

my site that i am trying to access is locally hosted using

the certs for the site are stored in ~/.lando/certs

when i go to the settings to add the certs, the file picker can’t see the directory (i know the dir is hidden, i can view the other hidden files in my home dir)

looks like postman is being run by my user, so i dont know why postman doesnt have access to some dirs (not just .lando, multiple other hidden dirs can’t be accessed, even though my user is the owner of all the files)
