Is this possible with lwc?

Hi everyone. Does anybody know if it is possible to find existing contacts by email and recordtypeid when using lwc for a custom prechat form on an embedded service?

Before the lwc we were able to do this with the standard prechat form by customising the embedded service snippet settings js file. 

Those customisations looked like this:

<script type='text/javascript'>
    var initESW = function(gslbBaseURL) {
        embedded_svc.settings.displayHelpButton = true; //Or false
        embedded_svc.settings.language = ''; //For example, enter 'en' or 'en-US'
        embedded_svc.settings.extraPrechatFormDetails = [
          {"label":"First Name",
          "transcriptFields":["PreChat_First_Name__c"]
          }, {
          "label":"Last Name",
          "transcriptFields":["PreChat_Last_Name__c"]
          }, {
          "label":"Email",
          "transcriptFields":["PreChat_Email__c"]
          }, 
            {
            "label":"RecordTypeId",
            "value":"0127F000000Hj9CQAS",
            }];
        embedded_svc.settings.extraPrechatInfo = [{
          "entityFieldMaps": [{
            "doCreate": true,
            "doFind": false,
            "fieldName": "LastName",
            "isExactMatch": false,
            "label": "Last Name"
          }, {
            "doCreate": true,
            "doFind": false,
            "fieldName": "FirstName",
            "isExactMatch": false,
            "label": "First Name"
          }, {
            "doCreate": true,
            "doFind": true,
            "fieldName": "Email",
            "isExactMatch": true,
            "label": "Email"
          }, {
            "doCreate": true,
            "doFind": true,
            "fieldName": "RecordTypeId",
            "isExactMatch": true,
            "label": "RecordTypeId"
          }],
          "entityName": "Contact",
          "saveToTranscript": "Contact",
          "showOnCreate": true
        }];
