I want to style my Image Field Button (Choose File) with CSS. Currently, its displaying in the default theme. I am using Bootstrap V5.0.1, Django V3.2.12, Python 3.7.6.

First, I tried to identify or add a class or id which I can add and style the button regularly but was unable to add as the button was added by Django Image Field. The Code in my forms.py is given below:
from django import forms
class ImageUploadForm(forms.Form):
image = forms.ImageField(label='')
Then I used the Hover functionality of the Chrome Developer Tools to identify any leads and found that the button and its area had 2 id's #file-upload-button and #id_image.

I tried to add CSS to the above-mentioned id's but did not get the result i desired. I want to style the Choose File Button Below also if possible can i add any bootstrap to the button, any help would be appreciated! Thanks.

HTML-Django Code
<div class="form-group text-center">
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form }}
<br>
<button type="submit" id="btnUpload" class="btn btn-primary" style="margin-top:20px;">Upload</button>
</form>
</div>
