Dealing with the scope of variables: inside loop - go

Question

As a JS dev jumping right into Go, I've hit a deadend trying to print multiple descriptions if the length of commits is more than one. I don't have much time left to complete this and I've been searching for longer than I wish. Any idea on how I could either restructure this or get this to work?
case github.PushPayload:
push := payload.(github.PushPayload)
repo := push.Repository.Name
owner := push.Repository.Owner.Login
ownerUrl := push.Repository.Owner.HTMLURL
ownerAvatar := push.Repository.Owner.AvatarURL
ref := push.Ref
refTrim := strings.Replace(ref, "/.*/", "", -1)
commits := push.Commits
for _, commit := range commits {
message := commit.Message
url := commit.URL
id := commit.ID
idShort := id[0:6]
committer := commit.Committer.Username
description := "[`" + idShort + "`](" + url + ") " + message + " - " + committer
}
if len(commits) == 1 {
discord.ChannelMessageSendEmbed(channelID, &discordgo.MessageEmbed{
Color: 0x00B1FF,
Description: description,
Title: "[" + repo + ":" + refTrim + "] 1 new commit! 🔧",
Author: &discordgo.MessageEmbedAuthor{
Name: owner,
URL: ownerUrl,
IconURL: ownerAvatar,
},
})
} else {
discord.ChannelMessageSendEmbed(channelID, &discordgo.MessageEmbed{
Color: 0x00B1FF,
Description: description,
Title: "[" + repo + ":" + refTrim + "] " + string(len(commits)) + " new commits! ⚒️",
Author: &discordgo.MessageEmbedAuthor{
Name: owner,
URL: ownerUrl,
IconURL: ownerAvatar,
},
})
}
PS: Ignore string(len(commits)) I know that's incorrect, I'm stuck trying to figure this out first and foremost. Also ignore: refTrim := strings.Replace(ref, "/.*/", "", -1), which isn't correct either.

you have to declare description variable before the loop and then add commit descriptions to it as below inside the loop.
Note: I emitted other code blocks here.
description := ""
for _, commit := range commits {
description = description + "commit description here"
}
description += "commit description here" also can be used inside the loop. But I have added above to more understanding.
