Migrating from zsh to fish - config file syntax [closed]

I am migrating from zsh to fish. I am still new to the fish shell.

I had the below in my .zshenv

export GPG_TTY=$(tty)

And the below in my .zshrc

#To automatically use bicon.if ! [[ "$(ps -p $(ps -p $(echo $$) -o ppid=) -o comm=)" =~ 'bicon'* ]]; then bicon.binfi

I am not sure what is the fish equivalent syntax for both.

Can someone please help me to transport these over to my fish config?
