How can I make tshark to use the custom HTTP headers?

edit

By wireshark, I know how to define custom http headers on GUI. After doing that, the file "custom_http2_header_fields" would be generated.

Then how can I make tshark to recognize this custom http header?

Do I need to put this file to specific directory (I tried the folders of "Personal configuration" as well as "Global configuration" got by command "tshark -G folders", but seems that is helpless)?

Or are there any command line options can do this?

Appreciate your help.

The version of my tshark: 3.6.0.
