How to preserve previous session after running `exec`

[Shaygan Hooshyari]

• I am using the latest release of AWS Vault
• I have provided my .aws/config (redacted if necessary)
• I have provided the debug output using aws-vault --debug (redacted if necessary)

I have a question about how do you preserve the previous shell after running exec command. I understand that exec creates a subshell, and if I have a python virtual env activated it will be deactivated in the subshell.

Here's an example:

❯ which python
/Users/glyphack/.virtualenvs/data-products-infra/bin/python

❯ aws-vault exec bren-sa-na-prod
Starting subshell /usr/local/bin/fish, use `exit` to exit the subshell

❯ which python
/Users/glyphack/.pyenv/shims/python

Could you provide some resources on how can I change my config so that the virtual env is kept activated?
