Export with LUT of previous year

However, Vide notification No. 35/2020-Central Tax, dated 03.04.2020, issued under the provisions of 168A of the CGST Act, except for few provisions covered in exclusion clause, any time limit for completion or compliance of any action which falls during the period from the 20th day of March, 2020 to the 29th day of June, 2020, and where completion or compliance of such action has not been made within such time, has been extended to 30th day of June, 2020.

So on the basis of this, can we Export without IGST without getting LUT (that is using LUT of FY 19-20)?
