I installed odoo15 on my local PC and cloud server respectively. Now I try to export the pages designed in cloud server and import it in the local PC. I followed the procedures in https://www.youtube.com/watch?v=Xh3iCzLAH30 but unfotunately, I go to technical - views, but did not find the import button as in the video. I checked that  base_import is installed, and in the setting both import & export are also checked. Could somebody help me find out the way to make import button appear in the technical views page. Thank you very much in advance.
