how to set forecasting seasonality with fewer observations in PowerBi

Question

i have fewer data points (9 data points, data coming from every week) and have to forecast for the next 4 points. I have no idea to set seasonality for this. Normally if we have daily, weekly, monthly data and we put 365,52 and 12 as seasonality respectively. How to set seasonality if only 9 data points are available.

Data:

{'Week': {0: Timestamp('2022-03-07 00:00:00'),
  1: Timestamp('2022-03-14 00:00:00'),
  2: Timestamp('2022-03-21 00:00:00'),
  3: Timestamp('2022-03-28 00:00:00'),
  4: Timestamp('2022-04-04 00:00:00'),
  5: Timestamp('2022-04-11 00:00:00'),
  6: Timestamp('2022-04-18 00:00:00'),
  7: Timestamp('2022-04-25 00:00:00'),
  8: Timestamp('2022-05-02 00:00:00')},
 'Runs': {0: 191,
  1: 190,
  2: 198,
  3: 245,
  4: 179,
  5: 219,
  6: 195,
  7: 159,
  8: 177}}

Please take a look and give some guidance.
