PMP Practice: Re-assess continually to ensure impediments are being addressed

Cedar Tanaka is managing a hybrid project for Macaron Voltage Labs to redesign their customer portal. The development team has completed three sprints but needs access to the legacy customer database to integrate authentication features. The database is controlled by the IT Operations group, led by Viktor Novak, who has repeatedly delayed granting access, citing security concerns and competing priorities. The team cannot proceed with the next sprint without this access, and Viktor has not responded to the last two emails from the team lead. Lila has already reviewed the access requirements with the team and confirmed they follow the company's security protocols. What should Lila do to remove this impediment?
