Create renditions through action scripts

Question

I have created some custom renditions for assets in Content Hub,so whenever i upload new asset these renditions will be created automatically, but for existing assets we need to click on refresh rendering button/link for that(to create new renditions).

Is there any way that we can write some action script which will be called from some trigger on asset modification and start a job and create these new renditions?

Thanks

Got an awesome blog, You can take the reference from that

Updating my answer as above blog is not working anymore and because of that reason I already got 3 down votes

Update : Attaching the code snippet::

var targetIds = new List<long>
{
    32637
    // use a query to get your ids
};

var jobEntity = await client.EntityFactory.CreateAsync("M.Job").ConfigureAwait(false);
jobEntity.SetPropertyValue("Job.Type", "MassEdit");        
jobEntity.SetPropertyValue("Job.State", "Created");       
jobEntity.SetPropertyValue("Job.Condition", "Pending");       
jobEntity.SetPropertyValue("Job.TargetCount", Convert.ToInt64(0));       
jobEntity.SetPropertyValue("Job.TargetsCompleted", Convert.ToInt64(0));       
var jobId = await client.Entities.SaveAsync(jobEntity).ConfigureAwait(false);       

// then the description
var descriptionEntity = await client.EntityFactory.CreateAsync("M.JobDescription").ConfigureAwait(false);  
     
string jobConfiguration = $@"{{
           ""$type"": ""Stylelabs.M.Base.MassEdit.MassEditJobDescription, Stylelabs.M.Base"",
    ""Operations"": [
        {{
            ""$type"": ""Stylelabs.M.Base.MassEdit.RefreshRenditionsOperation, Stylelabs.M.Base"",
            ""Renditions"": [{string.Join(",", renditionNames.Select(name => $"\"{name}\""))}],
            ""FailedOnly"": false,
            ""RefreshHistory"": false,
            ""RefreshSubfiles"": false
        }}
    ],
    ""FinalizeOperations"": [],
    ""Targets"": [{string.Join(",", targetIds)}]
}}";       
    

descriptionEntity.SetPropertyValue("Job.Configuration", JToken.Parse(jobConfiguration));       

var jobRel = descriptionEntity.GetRelation("JobToJobDescription", RelationRole.Child);       
jobRel.SetIds(new long[] { jobId });              
var descriptionId = await client.Entities.SaveAsync(descriptionEntity).ConfigureAwait(false);              

// logger.LogInformation($"Created job description {descriptionId}");       

// And finally update the job (we can only do that after the description is created)           

var loadConfig = new EntityLoadConfiguration()        
{        
    PropertyLoadOption = new PropertyLoadOption("Job.State", "Job.TargetCount"),
    RelationLoadOption = RelationLoadOption.None,
    CultureLoadOption = CultureLoadOption.Default       
};         
jobEntity = await client.Entities.GetAsync(jobId, loadConfig).ConfigureAwait(false);       
jobEntity.SetPropertyValue("Job.State", "Pending");       
jobEntity.SetPropertyValue("Job.TargetCount", Convert.ToInt64(targetIds.Count));       

await client.Entities.SaveAsync(jobEntity).ConfigureAwait(false);
