How to create dynamic array using checkbox and mapping in React JS?

I am mapping a list of formations and i would like to create a dynamic array in onChange when i select a checkbox.
The objectif is to update my organization with formations they can dispensed. do not be careful about formation.name, it was just to see if my mapping works :)

I would like to have something like

{
  {
     formation.id: idFormation1,
     dispensed: true
  },
  {
     formation.id: idFormation2,
     dispensed: false
  }
}

Here the code of the modal:

   <Modal
        cancelSubmitButton={cancelSubmitButton}
        title={title}
        titleButtonModal={titleButtonModal}
        submit={onSubmit}
        classModal={classes.modal}
        classButton={'button-formation ' + classes.button}
        icon={icon}
        activeIcon={activeIcon ? activeIcon : false}
        disabledModalButton={''}
        openedFunction={onOpen}
        titleButton={titleButton ? titleButton : title}
        closedFunction={closedFunction}
        classIconButton={classIconButton}>
        <Grid container spacing={1}>
          <Grid item xs={6}>
            <span className={classes.breakWord}>
              <b>Raison sociale :</b> {organization.name}
            </span>
          </Grid>
          <Grid item xs={6}>
            <span className={classes.breakWord}>
              <b>NDA :</b> {organization.activityDeclaration}
            </span>
          </Grid>
        </Grid>
        <TableContainer component={Paper}>
          <Table aria-label="collapsible table">
            <TableHead>
              <TableRow>
                <TableCell classes=>

            <TableBody>
              {formations && formations.length >0 && formations.map(formation => (
