Flowable ui starter 404 not found


I’m trying to add the flowable ui starter to my flowable event registry demo, but if I navigate to http://localhost:8080/flowable-task I get a 404 , I tried with different starters and different urls. What did I do wrong?

my build.gradle looks like this

plugins {
	id 'org.springframework.boot'
	id 'io.spring.dependency-management'
	id 'java'
	id 'war'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories {

dependencies {
	compile group: 'org.springframework.boot', name: 'spring-boot-starter-amqp', version: '2.3.2.RELEASE'

	implementation 'org.springframework.boot:spring-boot-starter-web'
	implementation group: 'org.springframework.boot', name: 'spring-boot-devtools', version: '2.4.4'
	implementation group: 'org.springframework.boot', name: 'spring-boot-starter-actuator', version: '2.4.4'
	providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
	testImplementation('org.springframework.boot:spring-boot-starter-test') {
		exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'

	compile group: 'org.flowable', name: 'flowable-spring-boot-starter-process', version: '6.5.0'
// https://mvnrepository.com/artifact/org.flowable/flowable-ui-modeler
	implementation group: 'org.flowable', name: 'flowable-ui-task', version: '6.5.0', ext: 'pom'
	runtimeOnly "com.h2database:h2"
	compile group: 'org.flowable', name: 'flowable-jms-spring-executor', version: '6.5.0'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"

test {

Adding the flowable-ui-task dependency is not enough: you need to add the ‘flowable-spring-boot-starter-ui-task’ dependency to embed it into a Spring Boot application.
