How to ungroup routes into different files in Echo?

[lolo02afon]

Please help. The task is to ungroup the code so that there are eventually three route files: one with route groups, and two with routes for learn_personal and count_private

At the moment I have this code:

package main

import(
"lolo/pjt_count_private/handlers_2"
"lolo/pjt_learn_personal/handlers_1"

"github.com/labstack/echo/v4"
)

func main() {
e := echo.New()

g_learn_personal := e.Group("/learn_personal")
g_learn_personal.GET("/index", handlers_1.F_index)
g_learn_personal.GET("/user", handlers_1.F_user)
g_learn_personal.GET("/admin", handlers_1.F_admin)

g_count_private := e.Group("/count_private")
g_count_private.GET("/index", handlers_2.F_index)
g_count_private.GET("/user", handlers_2.F_user)
g_count_private.GET("/admin", handlers_2.F_admin)

e.Logger.Fatal(e.Start(":1323"))
}
