r - Is there any function to graph trends of individuals as well as the average trend of panel data?

Question

I have a panel dataset:

 ID Year BankName Totalassets
1  1 2017  ABNAmro      393171
2  1 2018  ABNAmro      407373
3  1 2019  ABNAmro      394482
4  2 2017      AIB      145222
5  2 2018      AIB      103122
6  2 2019      AIB       90062

I want to plot the trends of total assets of each bank as well as the average trend of all banks throughout the years, like this:

Do you know how to do that or any threads that have discussed this topic? R is super new to me so I need your help.

Thanks in advance!
