How to generate an access token from a service account created from firebase app using Go

There's a way to generate an access token using a service account file generated from the firebase app. Source: https://firebase.google.com/docs/database/rest/auth#python.

Is there a way to generate an access token from a Go SDK?

[Update]
I've studied their doc and reached this level and am kinda lost on how to fetch/get the access_token from that point.

package main

import (
	"context"
	"fmt"
	"math"
	"regexp"
	"sort"
	"strconv"
	"strings"

	"google.golang.org/api/oauth2/v2"
	"google.golang.org/api/option"
)
func main() {
	ctx := context.Background()
	oauth2Service, err := oauth2.NewService(ctx, option.WithCredentialsFile("service-account.json"), option.WithScopes("https://www.googleapis.com/auth/userinfo.email", "https://www.googleapis.com/auth/firebase.database"))

	if err != nil {
		panic(err.Error())
	}
	tokenInfo, err := oauth2Service.Tokeninfo().Do()

	if err != nil {
		panic(err.Error())
	}
	
	fmt.Println(tokenInfo)
}

Just got the solution after digging more into their docs:
Doc to transport package

	ctx := context.Background()
	creds, err := transport.Creds(ctx, option.WithCredentialsFile("service-account.json"), option.WithScopes("https://www.googleapis.com/auth/userinfo.email", "https://www.googleapis.com/auth/firebase.database"))

	if err != nil {
		panic(err.Error())
	}

	ts := creds.TokenSource

	tok, err := ts.Token()

	if err != nil {
		panic(err.Error())
	}

	fmt.Printf("access_token %v", tok.AccessToken)
