hi,
Insteaf of having guar like canActivate [ OktaAuthGuard, MyAppGuard ],
is it possible to have a unique guard : canActivate [ MyAppGuard ] where MyAppGuard call OktaAuthGuard like this

export class AppGuard implements CanActivate {
// the oktaAuthGuard make its job then my guard do its job next
if (OktaAuthGuard.canActivate() ) {
// my appGuard job
if(myConditionOfMyGuard()) {
return true;
} else {
this.router.navigate([’/somewhere’]);
return false;
}
}
}
