How to config debugger in Goland

When I use "Step Into" in the debugger, it jumps into functions/types from outside my project (stdlib, vendor, etc.). How can I configure the debugger to step only into my own code? That's my code.

    
        package main
    
        import (
        "encoding/json"
        "fmt"
        "os"
        )
    
        var cmdAdd string
        var surname string
    
        type Task struct {
        ID     string `json:"id"`
        Name   string `json:"name"`
        Status string `json:"status"`
        }
    
        func main() {
        fileTaskTracker := "tasks.json"
        if len(os.Args) < 2 {
            fmt.Println("Please provide a command add, update or delete")
            return
        }
        tasks := []Task{}
    
        // Marshal the struct to JSON
        jsonData, err := json.MarshalIndent(tasks, "", "  ") // Use MarshalIndent for pretty-printing
        if err != nil {
            fmt.Println("Error marshalling JSON:", err)
            return
        }
        err = os.WriteFile(fileTaskTracker, jsonData, 0644) // 0644 sets file permissions
        if err != nil {
            fmt.Printf("Error writing to file: %v\n", err)
            return
        }
        fmt.Println(jsonData)
        }

I set break point on line:

    jsonData, err := json.MarshalIndent(tasks, "", "  ") // Use MarshalIndent for pretty-printing
