How can I edit the region of an aws lambda function already created?

Question

I have created a lambda function via the web console and when I try to setup the trigger S3 using my bucket I got this error:

Is obvious that I need to change the region because my bucket is on "us-west-2" and the function is on "us-east-1" but this is the thing:

In the creation process I did not see an option to select the region for the function and in edition mode I have checked all places searching an option to update the region but I could not find it.

What I am missing?

Like Mark B said in comments. You need to select the region before to create the function.

On the AWS Lambda "admin home" page there is a dropdown
