R plot date data multiple geom_line

Plotting the below data. trying to include the lines per tech, Without using the facetwrap.
Plot both tech and files per enm --

Using below code -

data %>% group_by(Date, emmm, tech, filescount) %>%  summarize(filescount = sum(filescount)) %>% ggplot(aes(Date, emmm, tech, color = filescount)) + geom_point(size = 2.4, alpha = 0.5) + geom_line(aes(x = Date, y = emmm), size = 1,  alpha = 0.4, stat = "identity", na.rm = TRUE) 

gives an image like -

Any way to present with both tech and showing the filescount, i.e - geom_line per tech and filescount !

# Your given test data as a dataframe

    filescount = c(1136, 3475, 317, 1136, 8899, 296, 1136, 9034, 292)
)

# Create a dataframe to plot
df_sum <- df %>%
    group_by(emmm, tech, Date) %>%
    summarize(total_files = sum(filescount), .groups = 'drop')

# Plot the data
ggplot(df_sum, aes(x = Date, y = total_files, group = interaction(emmm, tech), color = interaction(emmm, tech), linetype = interaction(emmm, tech))) +
    geom_line() +
    geom_point() +
    labs(x = "Date", y = "Files per Tech", color = "Tech", linetype = "Tech") +
    scale_color_discrete(name = "Emmm - Tech", labels = c("vnmenm1 - 3g", "vnmenm1 - 4g", "vnmsgsn1 - 4g")) +
    scale_linetype_discrete(name = "Emmm - Tech", labels = c("vnmenm1 - 3g", "vnmenm1 - 4g", "vnmsgsn1 - 4g")) +
    theme_minimal()
