how to print [][]interface{} in go?

i am trying to print the data from this page: https://www.rolimons.com/api/activity

this is how it looks:

{"success":true,"activities":[[1624720645,1,6815676017,1080,1047,563399],[1624720637,1,6807138720,915,893,563398],[1624720633,1,6803395856,683,687,563397],[1624720633,1,2409285794,44853,44867,563396],[1624720623,1,71484026,2172,2114,563395],[1624720613,1,9254254,6620,6632,563394],[1624720611,1,124472052,1054,1048,563393],[1624720581,1,6803403781,671,653,563392],[1624720578,1,44113968,972,980,563391],[1624720527,1,332772333,2274,2264,563390]],"activities_count":10}

i used https://mholt.github.io/json-to-go/
to get:

type data struct {
	Success         bool            `json:"success"`
	Activities      [][]interface{} `json:"activities"`
	ActivitiesCount int             `json:"activities_count"`
}

this is my code:

	resp, err := http.Get("https://www.rolimons.com/api/activity")
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()
	var data *data
	error := json.NewDecoder(resp.Body).Decode(&data)
	if error != nil {
		panic(error)
	}
	println(data.Activities)

but it gives me this:

[11/13]0xc0002bc000

but i want to make it print the 4th and the 5th value for example:

{"success":true,"activities":[[1624720645,1,6815676017,1080,1047,563399]

would be:

1080,1047

As you can see in this example, you can use fmt.Printf("%+v\n", data.Activities) to print the data of that slice.

To print only the wanted cell, use indices to address them.

You can address slice indices with square braces [] like so:
data.Activities[0][4] to access the 5th element of the first nested slice.
