Failed to analyze trim function INT as argument

Failed to analyze Big Query Trim function if INT passed as argument.
Select trim(5) is an incorrect statement because integer is not supported here as argument it should through an error.

Start by reproducing the GoogleSQL analyzer result for the expression `SELECT TRIM(5)`. Trace the trim function analysis path and its existing argument validation, then confirm that an integer argument produces an error rather than being accepted.
