If you're using one of the product indicator approaches, you might want to use some lavaan 
functions on top of the estimated lavaan-object. 
To do so you can extract the lavaan-object using the `extract_lavaan()` function.

```{r}
library(lavaan)

m1 <- '
# Outer Model
X =~ x1 + x2 + x3
Y =~ y1 + y2 + y3
Z =~ z1 + z2 + z3

# Inner model
Y ~ X + Z + X:Z
'

est <- modsem(m1, oneInt)
lav_object <- extract_lavaan(est)
bootstrap <- bootstrapLavaan(lav_object, R = 500)
```
