How do UAE business owners actually handle USD payments and FX? Genuinely curious

Running some research on UAE business banking and would love to hear from actual business owners here rather than read another generic article.

Specific questions I am trying to understand:

When you receive USD or EUR from an international client, where does it land and what happens to it? Do you have a way to hold it or does your bank auto-convert to AED?

How do you handle paying international suppliers - is it a SWIFT wire every time, or have you found a better way?

What is the most painful part of your current banking setup as a UAE business?

Building something in this space and want to understand the real problem before building the solution. Happy to share what I am working on with anyone who is curious.
