How to setup Google Analytics 4 for Multiple GTM Environments (Dev, Prod)

I need solution to set up Google Analytics4 for my website with multiple GTM environments (Dev, Prod).

Earlier for Universal Analytics we have solved this by setting up Lookup Table & tracking IDs (for multiple environments)

Configured till now:

1. created properties for (Dev & Prod) n set up the data streams(Prod & Dev domains) in Google Analytics
2. Created custom environments for Dev & Prod in GTM
3. set up the Google Analytics 4 configuration tag with measurement ID (prod)
4. Added GTM environment code snippets for ( Dev & Prod)

we can see both Dev & Prod data in GA reports. Which messing entire reports. So we need to forward prod data to GA Prod property n Dev data Dev property.
