Using flow to split a Sharepoint List column and get result copied to same list in another column

[Chad1980]

Hi

Good day everyone! Thank you in advance for reading and helping with my automate challenge. I basically need to get the delimited text result from a SharePoint list column pasted on the same SharePoint list but another column using automate. I need to do this due to limitation in PowerApp delegation (does not work on calculated column).

The text value of column 1 is in this format: mytest+identifier1@email.com

FYI, column 1 is a lookup type column.

I'd like the text result on column 2 in this format: identifier1

Regards,
