How to use the @sourcegraph/codeintellify/lib/token_position.getCodeElementsInRange function in @sourcegraph/codeintellify

locationPositions.pipe(withLatestFrom(this.codeViewElements)).subscribe(([position, codeView]) => {
                codeView = codeView! // locationPositions is derived from componentUpdates, so this is guaranteed to exist
                const codeCells = getCodeElementsInRange({
                    codeView,
                    position,
                    getCodeElementFromLineNumber: domFunctions.getCodeElementFromLineNumber,
                })
                // Remove existing highlighting
                for (const selected of codeView.querySelectorAll('.selected')) {
                    selected.classList.remove('selected')
                }
                for (const { line, element } of codeCells) {
                    this.createLineDecorationAttachmentDOMNode(line, element)
                    // Highlight row
                    const row = element.parentElement as HTMLTableRowElement
                    row.classList.add('selected')
                }

                // Update overlay position for discussions gutter icon.
