### Is there an existing issue for this?

- [X] I have searched the [issue tracker](https://www.github.com/Kong/insomnia/issues) for a bug that matches the one I want to file, without success.

### Insomnia Version

2021.5.2

### What operating system are you using?

macOS

### Operating System Version

macOS Catalina 11.5.2

### Installation method

download app from insomnia

### Last Known Working Insomnia version

_No response_

### Expected Behavior

{
"expr": [
"a =[Response > Body attribute]"
]
}

### Actual Behavior

{
"expr": [
"a ={% jsonata_response '', '', 'never' %}"
]
}

### Reproduction Steps

1) create request 1, it should generate results such as a login token
2) refer to request chaining by typing in Response > body attribute , application would return {% jsonata_response '', '', 'never' %}"
3) all function is undefined

### Additional Information

There is no drop down menu to select attribute or map chained responses

Reproduce the issue using the listed steps in Insomnia 2021.5.2 on macOS, starting with request chaining and the Response > Body attribute selector. Check that the selector presents the expected menu instead of the raw JSONata expression; done when chained response attributes can be selected and inserted correctly.
