Hi Kunaal,
For this use case you can leverage message templating.

Our Poll Bot implementation uses a data object which contains answers to a poll, which is a list of strings, https://github.com/SymphonyPlatformSolutions/symphony-poll-bot-java/blob/main/src/main/java/com/symphony/devrel/pollbot/command/CreatePollFormReply.java#L145-L152

        // Construct poll form and blast to audience
        Map<String, ?> data = Map.of("data", PollBlastData.builder()
            .id(poll.getId())
            .question(poll.getQuestionText())
            .answers(poll.getAnswers())
            .creatorDisplayName(poll.getCreatorDisplayName())
            .timeLimit(poll.getTimeLimit())
            .build());
        Message message = Message.builder().content(pollService.getMessage("poll-blast-form", data)).build();

We then use a Freemarker template to iterate on the answers field to produce the respective number of buttons with labels, https://github.com/SymphonyPlatformSolutions/symphony-poll-bot-java/blob/main/src/main/resources/templates/poll-blast-form.ftl#L11-L13

    <#list data.answers as answer>
        <button name="option-${answer?index}" type="action">${answer}</button><br/>
    </#list>
