I'm building a Slack bot app. I want every time a user opens the dialogue with the bot, the bot will automatically say something like "Hello! Please ask me a question". I think I should use the event API: https://api.slack.com/events to listen to the user action, but which event I should capture?

Use AppHomeOpenedEvent Class .
When you click on your bot or App in the Apps Section of Slack . The Moment You Click on Home tab , below code in come in action
Below is the Sample Code In Slack Bolt SDK Java
app.event(AppHomeOpenedEvent.class, (req, ctx) -> {
var logger = ctx.logger;
var userId = req.getEvent().getUser();
try {
// Call the conversations.create method using the built-in WebClient
var modalView = view(v -> v
.type("home")
.blocks(asBlocks(
section(s -> s.text(markdownText(mt ->
mt.text("*Welcome home, <@" + userId + "> :house:*")))),
section(s -> s.text(markdownText(mt ->
mt.text("About the simplest modal you could conceive of :smile:\\n\\nMaybe <https://api.slack.com/reference/block-kit/interactive-components|*make the modal interactive*> or <https://api.slack.com/surfaces/modals/using#modifying|*learn more advanced modal use cases*>.")))),
divider(),
context(c -> c.elements(asContextElements(
markdownText("Psssst this modal was designed using <https://api.slack.com/tools/block-kit-builder|*Block Kit Builder*>")
)))
))
);
var result = ctx.client().viewsPublish(r -> r
// The token you used to initialize your app
.token(AppConfigLoader.load().getSingleTeamBotToken())
.userId(userId)
.view(modalView)
);
// Print result
logger.info("result: {}", result);
} catch (IOException | SlackApiException e) {
logger.error("error: {}", e.getMessage(), e);
}
return ctx.ack();
});
