Hi @ShivaniB ,
Would you like to send an email to multiple recipients based on a multiple selection person column?
If so, please see the flow I created:

Details:
1. Initialize an array variable, append all the person Emails to the variable to create an array of Emails .
2. Use join function to concatenate emails with the ";" symbol and use the Emails string as the recipients of send an Email action.
join(variables('emails'),';')
Hope this helps.
