How do non-denominational Christians reconcile their stance with the fellowship of the Holy Spirit?

Some Christians identify as non-denominational and intentionally avoid affiliating with a specific church tradition or denomination. At the same time, Scripture speaks of the “fellowship of the Holy Spirit” (e.g., 2 Corinthians 13:14) and the unity of believers in Christ. How do non-denominational Christians understand and live out this fellowship of the Holy Spirit, given their rejection of denominational structures? Do they view fellowship as primarily spiritual and individual, or do they still see it as expressed in organized gatherings with other believers? I am particularly interested in perspectives from those who identify as non-denominational or have studied their theological approach.
