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

private async fetchSettingsFromVSCode(uri?: string): Promise {
        const configs = await this.fetchVSCodeConfiguration(uri || '');
        const [ cSpell, search ] = configs;
        const { exclude = {} } = search;
        const { ignorePaths = [] } = cSpell;
        const cSpellConfigSettings: CSpellUserSettings = {
            ...cSpell,
            id: 'VSCode-Config',
            ignorePaths: ignorePaths.concat(CSpell.ExclusionHelper.extractGlobsFromExcludeFilesGlobMap(exclude)),
        };
        return cSpellConfigSettings;
    }
