Not able to pass variables from Jenkins pipeline's script part to Ansible playbook

I have a problem with a partial pass of variables from Jenkins pipeline to Ansible playbook.

My variables in pipeline:

pipeline {
agent {
    label agentLabel
}
parameters {
    string(
        defaultValue: 'build/promo-api.zip',
        description: 'name and path of the artifact',
        name: 'ARTIFACT_ZIP')
    string(
        defaultValue: 'qa-promoapi-mbo.example.com',
        description: 'name and path of the vhost QA',
        name: 'QA_NGINX_VHOST')
}
stages {
        [...]
    stage ('Deploy') {
        steps {
            script {
                if (env.DEPLOY_ENV == 'staging') {
                    echo 'Run LUX-staging build'
                    def ENV_SERVER = '192.168.1.30'
                    def UML_SUFFIX = 'stage-mon'
                    sh 'ansible-playbook nginx-depl.yml --limit 127.0.0.1'                  
                    
                    echo 'Run STAGE SG deploy'
                    ENV_SERVER = 'stage-sg-mbo-api.example.com'
                    UML_SUFFIX = 'stage-sg'
                    sh 'ansible-playbook nginx-depl.yml --limit 127.0.0.1'                                              
                } else {
                    echo 'Run QA build'
                    def ENV_SERVER = '192.168.1.28'
                    def UML_SUFFIX = 'qa'
                    sh "ansible-playbook nginx-depl.yml --limit 127.0.0.1"  
                }
            }
        }
    }
}

Using this command I'm able to see in Ansible scope variables, defined in parameters part - ARTIFACT_ZIP and QA_NGINX_VHOST:

  tasks:
    - name: "Ansible | List all known variables and facts"
      debug:
        var: hostvars[inventory_hostname]

Problem is that I cannot pass variables from the script part - ENV_SERVER and UML_SUFFIX (these variables are unique to each server and must be changed accordingly).

In playbook vars are defined like this:

vars:
  params_ENV_SERVER: "{{ lookup('env', 'ENV_SERVER') }}"
  params_ARTIFACT_ZIP: "{{ lookup('env', 'ARTIFACT_ZIP') }}"
  params_STG_NGINX_VHOST: "{{ lookup('env', 'STG_NGINX_VHOST') }}"
  params_UML_SUFFIX: "{{ lookup('env', 'UML_SUFFIX') }}"

How to define variables correctly, to pass to Ansible playbook from Jenkins pipeline script block?

To make the env variables available to the bash task that executes ansible, you can use the withEnv step as follows:

[...]
script {
   if (env.DEPLOY_ENV == 'staging') {
       echo 'Run LUX-staging build'
       withEnv(["ENV_SERVER=192.168.1.30","UML_SUFFIX=stage-mon"]) {
           sh 'ansible-playbook nginx-depl.yml --limit 127.0.0.1'                  
       }
[...]
