Custom reporting

In the reports there is a field for attributes:

${position.attributes.toString().replaceAll(",", " ").replaceAll(bracketsRegex, "")}

This will display:

talkgroup=Groep A  battery=67.0  distance=68.73  totalDistance=160.15  motion=false

If i want only one attribute like talkgroup , how to change the position.attributes.to string?

Hello. Please tell me what changes need to be made to the report template to get a report in the example?

@rslord8, please don't duplicate your questions everywhere.

@Tananaev, sorry, I just wanted to ask people who had similar questions how they solved this issue.
Can you tell me what and where I need to change to get the report format shown in the screenshot?
