Hi Shruti,
You should go to Se80 - BSP Application - /UI2/USHELL - Page Fragments - shells - abap - cfg - sap - PersonalizationOff.json
Check below code and put false for contact support.
"renderers": {
"fiori2" : {
"componentData": {
"config": {
"enablePersonalization": false,
"enableTagFiltering": false,
"enableSetTheme": false,
"enableAccessibility": true,
"enableSendFeedback": false
}
}
}
}
}
Hope this helps,
Joseph
