I am trying to add headers and texts for my file created in GoogleDrive API.
I have array with summary which I want to add to my file. But on the left side (headers synapsis) I want to have only my headers from array. When I click on header I want my file to scroll to my title. My problem is, no in my headers on my felt side I also have description. How Can i make only headers (array keys) on left side and headers with text in my file content?

 $summary = [
            'Title' => "test title",
            'Length' => "3000",
            'Links' => "http://localhost:4200/#/clients/1/test1, http://localhost:4200/#/clients/1/test2",
            'Keywords' => "mouse, keyboard",
            'Description' => "detail description, etc."
        ];

        $this->googleDriveClient->addTextSummary($externalId, $summary);

code of addTextSummary:

public function addTextSummary(string $documentId, array $summary)
    {
        $requests = [];
        $headersLength = 1;
        foreach ($summary as $header => $text) {
            $requests[] = new Google_Service_Docs_Request([
                'insertText' => [
                    'endOfSegmentLocation' => [],
                    'text' => $header . "n"
                ]
            ]);

            $requests[] = new Google_Service_Docs_Request([
                'insertText' => [
                    'endOfSegmentLocation' => [],
                    'text' => $text . "nn"
                ]
            ]);

            $headersLength += strlen($header) + strlen($text);
        }

        $requests[] = new Google_Service_Docs_Request([
            'updateParagraphStyle' => [
                'range' => [
                    'startIndex' => 1,
                    'endIndex' => $headersLength + 1
                ],
                'paragraphStyle' => [
                    'namedStyleType' => 'HEADING_1'
                ],
                'fields' => 'namedStyleType'
            ]
        ]);

        $batchUpdateRequest = new Google_Service_Docs_BatchUpdateDocumentRequest([
            'requests' => $requests
        ]);

        $this->docsService->documents->batchUpdate($documentId, $batchUpdateRequest);
    }

in result I have file like this:

My goal is to have file content like in my attachment, but I want to remove text from left side, and have only titles there (only array keys like Title, Length, etc.). I dont want to have array values (like “test title”, “mouse, keyboard”) on my left side of file. How can I do this?
