How to set breakpoint in Delve with an init-command

In GDB, there is a flag --init-command which I can define a command like b dbConnection and it will be applied automatically after running the project. It sets the breakpoint on the dbConnection function.

I was looking for the same in Delve but I couldn't find it. The whole idea is instead of running dlv command and then telling where is my function and set the breakpoint there, I wanna give the function name before running dlv as init command like break pkg/db/connection.go:dbConnection. I can run fzf command to find the file easily and then I'll pass it to the dlv init command to set the breakpoint there.

    The flag is --init. For example:

    dlv debug --init <(echo b main.main)
