And possibly to align with nebula-studio(save to log rather than csv/json) and console(save to log rather than csv/json) to enable users easier to export this in ASCII way.

• scenario 1: 500 tags there and there are full tags scanned, the query exceeded the terminal emulator history line, it's not easy for them to share this profile result.(could use console with -e/ -f and redirect stdout, though, not everyone would figure out this way
• scenario 2: users are some nebula consumer without access with nebula-console(cluster prepared by another team and env is under big company's security rule to prevent from access graphd directly but only via studio), the profile query can only be done in studio but neither screen capture nor json result is readable for now.

These scenarios sound like feature requests to export the query result using the studio.
