How to use the cspell-lib.checkText function in cspell-lib

export async function checkText(filename: string, options: BaseOptions): Promise {
    const configGlob = options.config || defaultConfigGlob;
    const configGlobOptions = options.config ? {} : defaultConfigGlobOptions;
    const pSettings = globP(configGlob, configGlobOptions).then(filenames => ({source: filenames[0], config: cspell.readSettingsFiles(filenames)}));
    const [foundSettings, text] = await Promise.all([pSettings, readFile(filename)]);
    const settingsFromCommandLine = util.clean({
        languageId: options.languageId || undefined,
        local: options.local || undefined,
    });
    const info = calcFinalConfigInfo(foundSettings, settingsFromCommandLine, filename, text);
    return Validator.checkText(text, info.configInfo.config);
}
