How can I vertically center align the button within this grid? I've tried using vertical-align but it doesn't seem to work. I'm currently adjusting the vertical position of the button using top: "30%", but I'm looking for a better way to center it.

margin="normal"
/>
</Grid>
<Grid item xs={7}>
<Button variant="contained" color="primary" className={classes.button}>
Link AWS account
</Button>
</Grid>
</Grid>
</form>;
