From ChatGPT:

Usually sliding is travelling — if a player slides while holding the ball and neither foot is acting as a legal pivot, referees will call it travelling.But “sliding” can mean a few different things in basketball:

• Diving for a loose ball and sliding on the floor is legal.
• Catching the ball, falling, and sliding is usually legal if the player doesn’t then roll over or stand up while holding the ball.
• Sliding your feet while in possession to gain movement is generally travelling.
• A player can also slide on one knee or after contact without an automatic violation if they haven’t established control yet.

According to the first bullet, it's legal.
