Why can't i tip on Bolt?

I'm curious, why isn't it possible to leave a tip when using Bolt? Is this a limitation of the platform, or is there a specific reason behind this decision? As a frequent user, I've noticed that other payment methods often allow for tipping, which can be a great way to show appreciation for good service. So, can you shed some light on why this isn't an option with Bolt, and if there are any plans to introduce tipping functionality in the future?
