Yeah. Thanks Brian. It's a really good question. And obviously given the challenges of the pandemic, the insights change on a weekly basis, what we've seen is physicians are much more capable of staying open and treating patients and working through the pandemic, especially in comparison to how things were early in 2020 with the pandemic. That resilience really has allowed physician offices to continue to engage with sales professionals. So, our sales professionals, for the most part, have access to physicians. And to your question and your point, the dialogue has changed. If you recall, early in 2020 and then late in 2019 when we introduced both Nodify CDT and Nodify XL2, there was a lot of education, bringing physicians up to speed on a new test that was coming out, sharing all the clinical data we have. Now, when you look we're able to go back in and provide additional data. So, we're growing on that. And so, the CHEST data really allowed us to do that, where we can go back into positions and state, hey, look, we've got a building body of evidence. We've been able to show in a real world setting that we've reduced invasive procedures by 67%. We're not resting on that. We're going to continue to invest in clinical studies. And we think data is the only way to support physicians as they go out and present to physicians. We've also seen physicians start to reach out to us. So, when you think of that unsolicited outreach, that starts to be an indicator of awareness. And so, for us, coming out of the pandemic, we're pleased. We have a number of physicians in the past few weeks and months that have reached out, they've become aware of the test. They're seeing some of the presentations and publications. So, when it comes to access, we can't state -- the physicians' offices are open every single day. Obviously, we have to work with them. We have to continue to be transparent. But when they are open, we're conducting in-person meetings. And when they're not open, we don't stop. We've really adapted new sales methodology that supports us continuing to meet physician needs even while working remotely.
