Hi , @martusha
According to your description, you want to send an email to the people with the Pending data.
Here are the steps you can refer to :
(1)This is my test data in my SharePoint List:

(2)This is my flow:

[1]The "Get Items" and "initial variable" steps:

[2]The "Apply to each 2" action:

items('Apply_to_each')?['Email']
[3]The "Apply to each 3 " action:

union(variables('Persons'),variables('Persons'))
toLower(join(item()?['AssignedTo#Claims'],','))
toLower(items('Apply_to_each_3'))
(3)Then we can get the email for the aniyazhang:
