How to properly achieve dynamic parallel action with a declarative pipeline?

Currently, I'm going to need an implementation that must find all files within a directory and start a parallel task for every file found.

Is it possible to achieve this using declarative pipelines?

pipeline {
    agent any
    stages {
        stage("test") {
            steps {
                dir ("file_path") {
                    // find all files with complete path
                    parallel (
                        // execute parallel tasks for each file found.
                        // this must be dynamic
                        }
                    }
                }
            }
        }
    }
}

Managed to solve it with the following code:

pipeline {
    agent { label "master"}
    stages {
        stage('1') {
            steps {
                script {
                    def tests = [:]
                    for (f in findFiles(glob: '**/html/*.html')) {
                        tests["${f}"] = {
                            node {
                                stage("${f}") {
                                    echo '${f}'
                                }
                            }
                        }
                    }
                    parallel tests
                }
            }
        }       
    }
}
