Hi!
Here to help!
Please check this "checklist" first:
Use Handoff to continue tasks on your other devices - Apple Support
Each device is signed in to iCloud with the same Apple ID.
To see the Apple ID used by Apple Watch, open the Apple Watch app on your iPhone, then go to General > Apple ID.
Each device has Bluetooth and Wi-Fi turned on.
Each device has Handoff turned on.
Mac with macOS Ventura or later: Choose Apple menu > System Settings, click General in the sidebar, then click AirDrop & Handoff on the right. Turn on “Allow Handoff between this Mac and your iCloud devices.”
Mac with earlier versions of macOS: Choose Apple menu > System Preferences, click General, then select “Allow Handoff between this Mac and your iCloud devices.”
iPhone or iPad: Go to Settings > General > AirPlay & Handoff, then turn on Handoff.
Apple Watch: In the Apple Watch app on your iPhone, tap General and turn on Enable Handoff. Apple Watch supports handing off from your watch to your iPhone or Mac
Hope this helps!
Kind regards
