7## Call safeToRemove After Async Work
8 
9When using usePresence, always call safeToRemove after async work.
10 
11**Incorrect (missing safeToRemove):**
12 
13```tsx
14function AsyncComponent() {
15  const [isPresent, safeToRemove] = usePresence();
16 
17  useEffect(() => {
18    if (!isPresent) {
19      cleanup();
20    }
21  }, [isPresent]);
22}
23```
24 
25**Correct (safeToRemove called):**
26 
27```tsx
28function AsyncComponent() {
29  const [isPresent, safeToRemove] = usePresence();
30 
31  useEffect(() => {
32    if (!isPresent) {
33      cleanup().then(safeToRemove);
34    }
35  }, [isPresent, safeToRemove]);
36}
37```
