[SOLVED] How to delete a mail from Mailgun API domain queue?

How to delete a mail from Mailgun API domain queue?

I'm writing a module in PHP Laminas to send mails through Mailgun API. I'm able to send the mail as well as list the pending queue. I want to delete a particular mail in mailgun using message-id. Can someone please guide me if its even possible? If yes, how?

The closest I've got in terms of documentation is clearing the domain queue which isn't what I want. https://help.mailgun.com/hc/en-us/articles/360012487654-How-Can-I-Delete-Messages-From-the-Queue-

Below is the code I've written to send the mail using Mailgun.

    /**
     * MailgunApiSendRequest constructor.
     *
     * @param MailgunApiModel $mailgunApiModel
     * @param MailgunApiSendResponse $mailgunApiSendResponse
     */
    public function __construct(MailgunApiModel $mailgunApiModel, MailgunApiSendResponse $mailgunApiSendResponse)
    {
        $this->mailgunApiModel = $mailgunApiModel;
        $this->mailgunApiSendResponse = $mailgunApiSendResponse;
    }

    /**
     * @return MailgunApiSendResponse
     * @throws ClientExceptionInterface
     */
    public function send(): MailgunApiSendResponse
    {
        /** @var Mailgun $mailgun */
        $mailgun = $this->getMailgunApiClient()->create();

        /** @var array[] $params */
        $params = [
            "from" => $this->getMailgunApiClient()->getFromEmail(),
            "to" => $this->getMailgunApiModel()->getEmailAddress(),
            "subject" => $this->getMailgunApiModel()->getTitle(),
            "text" => $this->getMailgunApiModel()->getContent(),
            "o:deliverytime" => Carbon::now()->adddays(3)->toRfc2822String(),
        ];

        /** @var SendResponse $sendResponse */
        $sendResponse = $mailgun->messages()->send($this->getMailgunApiClient()->getEmailDomain(), $params);

        /** @var array[] $data */
        $data = [
            "id" => $sendResponse->getId(),
            "message" => $sendResponse->getMessage()
        ];

        $this->getMailgunApiSendResponse()->setResponse($data);

        return $this->getMailgunApiSendResponse();
    }

Below is the current status as per Mailgun Log.
