Problem about alert displayed in clangd

In the Diagnostics.cpp file of the clangd module in LLVM, there is a function called getDiagnosticDocURI that retrieves the URL address of a rule check. The code is as follows:

case Diag::ClangTidy: {
StringRef Module, Check;
std::tie(Module, Check) = Name.split('-');
if (Module.empty() || Check.empty())
return llvm::None;
return ("https://clang.llvm.org/extra/clang-tidy/checks/" + Module + "/" +
Check + ".html")
.str();
}

Now, I have defined several custom rules and have corresponding MD documents in the code repository. Therefore, in the clangd plugin in VSCode, when there is an alert, I want to be able to click on the hyperlink to go to the corresponding document. I modified the code as follows:

case Diag::ClangTidy: {
StringRef Module, Check;
if (Name.contains(StringRef("xxx-xxx"))){
std::string url = R"(https://open.codehub.xxx.com/innersource/DragonGlass/DragonGlass/files?ref%3Dmaster&isFile&%3Dtrue&filePath=clang-tools-extra/clang-tidy/xxx/docs/security/Check8Byte.md)";
return url ;
}


}
In the plugin, the alert is displayed, but when I check the hyperlink in the alert, it is always escaped as the following link:
https://open.codehub.xxx.com/innersource/DragonGlass/DragonGlass/files?ref%3Dmaster%26isFile%3Dtrue%26filePath%3Dclang-tools-extra%2Fclang-tidy%2Fxxxx%2Fdocs%2Fsecurity%2FCheck8Byte.md
This prevents me from being able to click on the hyperlink and access the specified website. How can I resolve this issue?
