Dealing with impostor syndrome. Help needed

Have any of you have felt like an imposter in your career? I'm an IT project manager, and this feeling of not being good enough hits me regularly. Even though I get positive feedback, I still feel like I'm not up to the mark. I am expected to understand a lot of different things, but I am not the ones directly doing the technical work. This can make it tough sometimes.

For me, there are a couple of things that trigger my imposter syndrome. Since we’re not always in the technical detail, I sometimes feel lost in meetings. It's impossible to know everything about every topic in real-time, but I still end up feeling like I lack the knowledge for my role. Also, managing teams and their dynamics is a big part of what we do. I think I do a decent job, but my current program doesn't have a dedicated team. We pull in resources from across the organization, so there's not much of a "team" vibe. This makes our sync-ups dull and the engineers seem disengaged. I've heard other PMs face the same issue, but it still makes me doubt my abilities.

Can anyone help me with this?
