Export Variable in Linux Terminal with Multiple Strings Terraform - shell

Question

I have this variable in Terraform called "example". The variable is a type of "list(strings)" and I need to export that variable in my terminal, when running Terraform plan (i cannot put the value in code, so I have to export it):
export VAR_example=""xyz", "abc", "123""
but when I run this^, it gives me error:
│ Error: Invalid number literal
│
│ on <value for var.example> line 1:
│ (source code not available)
│
│ Failed to recognize the value of this number literal.
╵
╷
│ Error: Extra characters after expression
│
│ on <value for var.example> line 1:
│ (source code not available)
│
│ An expression was successfully parsed, but extra characters were found after it.
Then, I tried exporting it like this:
export VAR_example='"xyz", "abc", "123"'
Then, I got the error:
╷
│ Error: Extra characters after expression
│
│ on <value for var.example> line 1:
│ (source code not available)
│
│ An expression was successfully parsed, but extra characters were found after it.
Now, I am not sure how to export it at all. Any solution would be helpful.

Since it is a list of strings, you could provide it this way as well [1]:
terraform apply -var='examples=["xyz", "abc", "123"]'
However, since an environment variable needs to be used you could set it like:
export TF_VAR_examples='["xyz", "abc", "123"]'
Note that you need to prefix any environment variables with TF_ in order for Terraform to pick them up [2].
