Change FieldType from Number to Links?

I imported a csv table into my nocodb base (after I exported it from an external SQLite database separately). One of the columns consists of foreign keys. Nocodb automatically assigned the field type “Number” to this column. However, now I want to use this column as a link to another table. I want to change the FieldType for this column to “Links.” But “Links” is not an option in the drop-down menu when I go into the “Edit” menu for the field. Is it possible to convert this field into the Links field type?

Thank you!
