Help Needed - Grabbing text in between delimeters

Buckets84 I've had to do something like this before, pulling multiple different strings between delimiters in the filename and putting those strings into specific fields in a SharePoint List. My own solution was to run a Power Automate flow on new list entries, using the function "split" to extract specific strings, and then create an output that mapped to specific file properties (in the SharePoint List). I believe you can create a Flow right in PowerApps now. Check out the https://learn.microsoft.com/en-us/power-platform/power-fx/reference/function-split and see if this might work for your scenario.
