Depends on your home country because if there’s a tax treaty, it would supersede the laws.
Sometimes it’s phrased that any income from your home country while you’re in your guest country is only taxable in your home country. Other times it’s just credited against your local taxes (which could cover everything with a lot of paperwork, or could still leave you with an amount owing to cover the gap).
Sometimes even locally earned income is tax free, but that’s usually only for students.
Comparing to Barbados: they explicitly state in their "digital nomad" visa conditions: "You will not be liable to pay Barbados Income Tax and therefore will not be subject to any double taxation"[1] So they make it easy for you, no need to read through tax treaties.
