Cypher call with parameter failed

Example from the following link not support in cypher browser windows: my cypher version is 5.20,

Invalid input '(': expected "{" (line 2, column 6 (offset: 30))
"CALL (i) {"
^

UNWIND [4, 2, 1, 0] AS I

CALL (i) {

CREATE (:Person {num: 100/I})

} IN TRANSACTIONS OF 2 ROWS

RETURN i

In the manual it says:

The examples on this page use a variable scope clause (introduced in Neo4j 5.23) to import variables into the CALL subquery. If you are using an older version of Neo4j, use an importing WITH clause instead.
