Fill your email template default config value in etc/config.xml file with email template id which has been defined in etc/email_templates.xml file. in your case:

app/code/Blob/Withdrawal/etc/email_templates.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">

        <my_mobile_app>
            <withdrawal>
                <request_mail>my_mobile_app_withdrawal_request_mail</request_mail>
                <approve_mail>my_mobile_app_withdrawal_approve_mail</approve_mail>
                <reject_mail>my_mobile_app_withdrawal_reject_mail</reject_mail>

Replace your function code like this.

public function sendMail($emailTemplateVariables,$senderInfo,$receiverInfo,$type)
{
    $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;

    if ($type == 'request') 
    {
       $typeId = $this->_scopeConfig->getValue(self::XML_PATH_EMAIL_TEMPLATE_FIELD_REQUEST,$storeScope);
    } 
    elseif ($type == 'approve') 
    {
       $typeId = $this->_scopeConfig->getValue(self::XML_PATH_EMAIL_TEMPLATE_FIELD_APPROVE,$storeScope);
    } 
    else
    {
      $typeId = $this->_scopeConfig->getValue(self::XML_PATH_EMAIL_TEMPLATE_FIELD_REJECT,$storeScope);
    }
    $this->temp_id = $this->getTemplateId($typeId);
    $this->inlineTranslation->suspend();
    $this->generateTemplate($emailTemplateVariables,$senderInfo,$receiverInfo);
    $transport = $this->_transportBuilder->getTransport();
    $transport->sendMessage();
    $this->inlineTranslation->resume();
}

The issue seems to be that you are not passing template id temp_id in the following code while calling generateTemplate

$this->generateTemplate($emailTemplateVariables,$senderInfo,$receiverInfo);

and also you are not receiving the template id in the function

generateTemplate($emailTemplateVariables,$senderInfo,$receiverInfo)

Pass the value and receive it to fix the issue or declare temp_id as the global class variable.
