Dear moms, Can you tell me how to motivate a child to walk on their own?

Dear moms, Can you tell me how to motivate a child to walk on their own? We're already 1.5 years old but we still don't walk. I know that according to the norm until 18 months What have we done, he doesn't want to go by himself at all. He walks well with support. He doesn't crawl, but runs around the house ?‍↔️
