How to run this?

I would really like to try this out!

I've initiated a new project - go mod init, pasted the "simple app" code in a main.go file and changed the Groups value to match my Log Group.
I do have a working AWS Shell Environment, as I can run aws s3 ls and I get correct data.
When I run "go run main.go" nothing happens, I don't get any output either.

Can you please give me a bit more newb-friendly instructions?
Thank you!

It might be that your AWS defaullt profile is not properly configured.
You can follow the instructions here to see how it should be configured: https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html

Additionally, the sample code just returns on error.
In order to see what errors are occurring you can change

if err != nil {
    return
}

to

if err != nil {
    fmt.Println(err)
    return
}

Thanks @ghost for the query and @SteveOfficerSeccl for providing some tips.

@ghost, in addition to the change suggested by @SteveOfficerSeccl, you may need to make at least one other code change to produce output in your case. The following code is taken verbatim from the "A simple app" code in the README.md. Changing the log group probably won't be quite enough to provide input in most cases because there's also a | filter clause that is looking for messages that contain the text "foo"...

// Query the results.
s, err := m.Query(incite.QuerySpec{
	Text:   "fields @timestamp, @message | filter @message =~ /foo/ | sort @timestamp desc",
	Start:  start,
	End:    end,
	Groups: []string{"/my/log/group"},
	Limit:  100,
})

If you want to just verify that the simple sample app is pulling your logs by having it generate some output, I strongly suggest both dropping the | filter clause (delete the whole text | filter @message =~ /foo/ and following @SteveOfficerSeccl's advice to put in more appropriate error handling.
