Add fields() support for SOQL Builder

[randi274]

Is your feature request related to a problem? Please describe.
The new fields() feature for SOQL is awesome (v51+), and SOQL Builder half supports it. I see that ALL FIELDS is available, but would like to keep the fields() syntax of the query for simplicity.

Describe the solution you'd like
Being able to work with the fields() function in the SOQL builder without an error.

Additional context
Currently getting an error about a function expression when I toggle to SOQL Builder:

Thanks for the feedback @randi274 . This advanced syntax is not supported in the UI of SOQL Builder. However, you can still run the query. The message you linked is trying to convey that you can still run the query, but if you try to edit in the Builder UI, you will lose the advanced syntax. We'll think about reworking this messaging so it's clearer and maybe a bit less scary.

Let us know if you aren't able to run the query and get results.
