Hi @nidhi0104

we're currently blocked to implement this on our end, as not all ui5 web components do yet support the required attribute. I've created issues regarding this in their repository (e.g. SAP/ui5-webcomponents#5895)
Until then you can just add required to the input you pass as child to the FilterGroupItem (if it's supported).

E.g.:

<FilterGroupItem required label="Filter 1">
  <Input required />
</FilterGroupItem>
