How many times did Leif Erikson sail?

Leif Erikson is believed to have made at least one significant voyage to North America around the year 1000 AD, where he is credited with being the first European to set foot on the continent, specifically in a region he called Vinland, likely located in present-day Newfoundland, Canada. While there are accounts of his travels, the exact number of voyages he undertook is not well-documented, and most historical references focus primarily on this notable journey. Other than this expedition, details about additional sails are scarce.
