Is there option to filter completions by startsWith?

[Disimasa]

Hi! I want to add SQL functions autocompletion for my editor. However completions are filtered by any character entry. For example (on screenshot) there's an option 'system":

I'd like to have an option to filter by startsWith, so there'd be only strict entries (for "se" input only suggestions with "se" start). I guess I can add filtration of my suggestions inside registerCompletionItemProvider, however in that case it'd be necessary to trigger registerCompletionItemProvider at any character to have my custom filter. And I don't think it is a good idea. So is it a way to have such filtration on Monaco side?

I add suggestions like that:

CH_FUNCTION_SUGGESTIONS = [
{
    "label": "abs",
    "kind": 1,
    "insertText": "abs()",
    "insertTextRules": 4
  }, ...
]

completionProvider = $monaco.languages.registerCompletionItemProvider('sql', {
  triggerCharacters: ['.', '(', "'", '"'],
  provideCompletionItems: function (model, position) {
    return { suggestions: structuredClone(CH_FUNCTION_SUGGESTIONS) }
}
})

As you can imagine, this is a hot topic. See microsoft/vscode#64367 and its many other duplicated/related issues. Unrelated to VS Code, I'm personally not aware of a way to turn this off in Monaco.
