Where do I get data on how many people move from country to country globally in a year?

Question

I'm calculating total addressable market for a business that has to do with immigration. I need to know how many people physically relocate to another country with intention to settle there permanently, or alternatively how many people acquire legal immigrant status in a foreign country in a year, something like that.

OECD's website calls this permanent immigrant inflows, for 34 OECD countries they estimate it at about 4M a year, but I need data like this for worldwide. Is there a way to find it?

Bilateral migration data is available from sources such as the United Nations Population Division unit on International Migration, Migration Policy Institute, and Migration Data Portal. For example, the 2019 UN dataset for migrant stocks by origin and destination is available as .xlsx here.
