Julia 朱莉娅编码函数没有'；t将github form base64数据转换为UTF-8，如何转换'；有可能吗？

我尝试获取GitHub上的数据表单文件并读取它们

using HTTP
using JSON
using GitHub
using StringEncodings

# authenticate with GitHub to increase query limits
mytoken = ENV["GITHUB_AUTH"]
myauth = GitHub.authenticate(mytoken)

GitHub.repo("JuliaRegistries/General")
data_rootdir = GitHub.directory("JuliaRegistries/General","/")
data_rootdir = data_rootdir[1]
data_dir = GitHub.directory("JuliaRegistries/General", data_rootdir[3].path)
data_dir = data_dir[1]
manifest_file_data = GitHub.file("JuliaRegistries/General", joinpath(data_dir[3].path, "Deps.toml"))
data_Deps_file = decode(manifest_file_data.content, manifest_file_data.encoding)

在REPL中运行后，我得到以下代码：

julia> manifest_file_data = GitHub.file("JuliaRegistries/General", joinpath(data_rootdir[3].path, "Deps.toml"))
Content (all fields are Union{Nothing, T}):
  typ: "file"
  name: "Deps.toml"
  path: "A/ACTRModels/Deps.toml"
  encoding: "base64"

  download_url: HTTP.URI("https://raw.githubusercontent.com/JuliaRegistries/General/master/A/ACTRModels/Deps.toml")
  size: 664

然后我尝试转换我得到的数据错误：

 julia> data_Deps_file = decode(manifest_file_data.content, manifest_file_data.encoding)
ERROR: MethodError: no method matching decode(::String, ::String)
Closest candidates are:

您能帮助我理解如何正确地从GitHub获取数据吗。

标准库提供了处理base64编码字符串所需的一切。特别是功能：
