How to debug ncspot installed via flatpak?

[tomstefanski]

I do have ncspot installed via flatpak. I'd like to gather some logs for debugging purposes. Is the following supposed to do the job?

flatpak run io.github.hrkfdn.ncspot --debug /my/path/to/log_file.log

I don't get any logs within the file I specify, no matter if I choose the file which already exists or not.

I'll only add that the following commands work fine, i.e., they both print expected information onto the standard output.

flatpak run io.github.hrkfdn.ncspot info
flatpak run io.github.hrkfdn.ncspot --version
