Attestation, equivalency and licensing are different things
Attestation confirms that your degree is genuine. It doesn't tell a UAE body that your degree matches a local qualification, and it doesn't license you to practise. Some employers and regulators also ask for an equivalency or a professional assessment of their own, and those decisions rest with the relevant UAE authority.
We tell you at the start whether your situation is likely to involve more than attestation, so you can plan for it rather than discover it late.
