I am building a index which using SCIP which can provide a completion, however I want to run it along with TS language server in VS code.

There are way to do it using providers and triggering the intellisense by merging the completion but the problem is VS code always trigger ts server, I am running it in very large monorepo where ts server takes more time than what my index can provide.

Is there any way to run them in parallel and send winning one on UI first and then merge the slower later?
I tried to use [https://github.com/microsoft/TypeScript/wiki/Writing-a-Language-Service-Plugin](language server plugin) to add delay in ts server invocation but in that case as well my providers are called once ts server invocation is completed with delay.

Has someone done it before or have any idea how it can be done ?

Thanks in advance.
