Filecount - Telegraf test command not working

Hi Influx Community,

I have facing an issue with the Telegraf plugin filecount. I have it set up in my Telegraf configuration file, but when I am trying to run the telegraf --test command, it does not show up. Same with the command just below to make sure that only this plugin is in use:

telegraf --config telegraf.conf --input-filter filecount --output-filter influxdb --test

Do some know why it not working? MAybe the testing functionality not implemented in the filecount plugin?

Thank you for considering my issue,
