synchronizing vim-terminal pwd and vim pwd

Question

I'm looking for a way to synchronize the vim-terminal pwd and vim pwd. so for example

in normal terminal, navigate to directory a
>cd /a/

open vim terminal
> vim -c ":term ++curwin"

inside vim terminal navigate to directory /b/
>cd /b/

Now the vim pwd is /a/ and the vim terminal pwd is /b/.

is there a way to make it so that the vim-terminal cd will affect the vim pwd?

I found :h 'autoshelldir' but couldn't figure it out.
