zsh: env is not updated after a task execution

[tdragon]

I have a task to login to AWS and a few other services.
The task writes tokens to the .env.aws file.
In the mise.toml I have:

_.file = {path=".env.aws", redact=true}

I tried with "tools=true", but seems to be the same.

When I use fish it is enough to run the task to have env updated, so I can for example use aws s3 ls.
But in zsh I have to go out of the folder and then return back to refresh my environment: cd && cd -.
I tried to work this around with _.source script that source the .env.aws, but the script is also executed only when I enter the directory.

Is there a way to refresh the current shell variables after the task run?
